* Technocrat Pagination fixes Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * [TE/pagination] Add fixes from rebase to 0.4.3 previously uncommitted. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Add code to handle what appears to be a bug in Chromium. Content that's starting to overflow gets offset to the right of the existing content, for some strange reason. Recognise that as overflow too. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Correct a typo. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Add comparison of ranges in checking overflow equality. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Remove layout repeat check - shouldn't be needed and assumes node always set. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * If we're removing all the content from a row, remove the whole row. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Ignore colgroup tags in finding overflow. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Treat break-inside:avoid-column like avoid. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Remove old comment about not setting column widths. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Set the width from width attrib first if available. Better than getBoundingClientRect result in some cases. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Clone colgroup attrib if it exists when rebuilding tree. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Remember the start of the remainder separately to 'node'. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Handle siblingRangeStart also being the end of the doc. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Revert "Treat break-inside:avoid-column like avoid." This reverts commit 045655f09852c6a88bf7af652dbc72592b0c45c7. The commit breaks relaxtorium's sample and doesn't seem to fix anything else anymore. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Improve logic for deciding whether an entire row is being removed. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Setting columnWidth causes text to be cut off / no bottom border sometimes Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Improve readability, correct ignoreSides logic, default false.

Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Disable setting data-split-from to make tests pass for now. (Comment added in PR). Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Rebuild table rows taking account of row spans, initial cut. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Correct comment. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Get detected overflow's non overflowing text on original page. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Correct error in rowspan code. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Mathjax test needs to check math elements, not parents. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * needsBreak check adjustments. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * mustSplit DOES need to look at height, not bottom. (This is the does-it-fit-in-a-page check). Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Reenable data-split-from - gets justification right. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Further clarification on comments.

Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Fix relative paths to polyfill in specs Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Work on forced breaks. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * 38 pages. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Spec polyfill path correction. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * More footnote changes. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Getting 3rd footnote on footnote-policy.html Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Go back to modified main footnote.js.

Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Prevent getStart looping when we're just rendering overflow at the end. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Fix infinite loop, but correctly? Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Remove (I think wrongly) unsetting margin/padding top on split content. (To make tests pass). Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Work on page number recto/verso odd/even correction. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Correct English.

Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Get start should use breakToken.node It's the next node to be processed. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Check loops should stop at rendered. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Use this.avoidBreakInside. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Ensure break happens for colspan with break-inside avoid. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Make avoidBreakInside look at first node too. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Don't remove rowspan attrib at the moment. Needed for current use case but still need to check others. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * avoid-break-rowspan almost rendering right with our without break avoid. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Remove a dangling TR with no content. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Add math tag to dangling child pruning.

Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Get afterOverflowAdded adding footnotes correctly. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Continue named class on a footnotes only overflow page. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Break after recto testing polyfill path. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Clear MAX_PAGES and correct add page mistake. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Don't add named page classes on the basis of a node that will be in overflow. I think we should actually look for nodes in the page with the page attrib after overflow is removed, but let's revisit this later. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * No max pages. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Back to possible Chromium bug - footnotes.html text overflow missing o/wise. On footnotes.html, the "existence of similar letters" overflow on p5 isn't detected unless we look at the right bounds. Must be a better way but I don't know what it is yet. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Prevent split-from being set for content moved entirely to the next page. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Add overflow footnotes back. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Fix split-from being incorrectly set sometimes. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Don't start by assuming we need to go back to previous row. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Modify extracting footnote overflow for footnotes-counter-reset-page. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Update image snapshots for avoid-break-rowspan. Getting width consistent across the break now. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Update exceeding-rowspan-table image snapshots. Not obeying break-inside:avoid for tr in main. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * splits-tables-rowspan: Main doesn't obey rowspan correctly. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * generate-content/content-none. Images looks same but spec says different. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Fix typo. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Remove ignoreSides logic - no Chromium bug. It's display grid on the page. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Correct typo in footnotes range set. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Improve dangling, unsplit rendered child removal. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Invoke afterOverflowRemoved after all overflow is removed. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Make indexOfTextNode handle hyphenated text. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Take account of margins in textBreak for non-block parents. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Ensure split-to gets set when it should. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Don't clear the data-split-to in textBreak, so we don't confuse ourselves. If it is cleared and there is margin modified by the attribute, we might think there's overflow again. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Get setting the split-to and split-from attributes right. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Use overflow_after rather than split-to as the critieria for justifying? Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Fix typo in class name addition. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * In splits, just look for the data-ref. If text is broken, overflow-after will be on a parent but not the lowest text node (can't be). Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Update the rebuild-table-rows test - 3 pages now. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Correction to removing an entire footnote. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * named page spec image snapshot update. Can't see a difference but the code can. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Make isEntireNote handle startContainer is the footnote. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Another named page snapshot needs updating. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Update footnotes lastpage snapshot. Signed-off-by: Nigel Cunningham <nigel@technocrat.com.au> * Remove getOverflow hook - ended up being an unneeded addition. Signed-off-by: Nigel Cunningham <nigel@nigelcunningham.com.au> * Remove window.scrollTo debugging code. Signed-off-by: Nigel Cunningham <nigel@nigelcunningham.com.au> * Remove debugging commented out console log. Signed-off-by: Nigel Cunningham <nigel@nigelcunningham.com.au> * Remove console.log. Signed-off-by: Nigel Cunningham <nigel@nigelcunningham.com.au> * Remove unneeded comment / addition, update tests. Signed-off-by: Nigel Cunningham <nigel@nigelcunningham.com.au> * Add comment explaining the removal of parent containers. Signed-off-by: Nigel Cunningham <nigel@nigelcunningham.com.au> * One let ChildBounds to rule them all. Signed-off-by: Nigel Cunningham <nigel@nigelcunningham.com.au> * Use hyphen settings in indexOfTextNode. Signed-off-by: Nigel Cunningham <nigel@nigelcunningham.com.au> * Add test for copying column widths across a split (failing). Signed-off-by: Nigel Cunningham <nigel@nigelcunningham.com.au> * Make column-width test pass.
