Automatic update from web-platform-tests [LayoutNG] Add tests for text-overflow: ellipsis with scrolling These set of tests pass in Firefox but not in Chromium. They check what happens when you scroll an element with "text-overflow: ellipsis", right now in Chromium the rest of the content of the element is not visible at all (once truncated the text ellipsis is not moved). The solution would be to force a relayout during scrolling but it seems we prefer to keep current behavior to avoid performance issues on scrolling. The behavior is not mandatory according Both behaviors are allowed in the spec, so the tests are marked with the "should" flag: https://drafts.csswg.org/css-overflow/#ellipsis-scrolling Bug=745905 TEST=external/wpt/css/css-overflow/text-overflow-scroll-001.html TEST=external/wpt/css/css-overflow/text-overflow-scroll-rtl-001.html TEST=external/wpt/css/css-overflow/text-overflow-scroll-vertical-lr-001.html TEST=external/wpt/css/css-overflow/text-overflow-scroll-vertical-lr-rtl-001.html TEST=external/wpt/css/css-overflow/text-overflow-scroll-vertical-rl-001.html TEST=external/wpt/css/css-overflow/text-overflow-scroll-vertical-rl-rtl-001.html Change-Id: I975ca86dbdfedf92875c08736539fb2f33f68c54 Bug: 745905 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/2113495 Commit-Queue: Koji Ishii <kojii@chromium.org> Reviewed-by: Koji Ishii <kojii@chromium.org> Cr-Commit-Position: refs/heads/master@{#753508} -- wpt-commits: 86103a7fabf985763c122276a67615da0ced4b3c wpt-pr: 22388
