The following layout test is flaky on debug builds of all platforms. svg/text/bidi-reorder-value-lists.svg http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showExpectations=true&tests=svg%2Ftext%2Fbidi-reorder-value-lists.svg On Win/Linux the difference is slight. On Mac, the test output is clearly wrong in second, third and fourth rows. (The root cause may be different) I'm going to mark this test as failing. Probable cause: Not sure.
Marked LayoutTest bugs, bugs with Chromium IDs, and some others as WontFix. Test failure bugs still are trackable via TestExpectations or disabled unit tests.
