The following layout test is failing randomly on Linux. editing/selection/caret-at-bidi-boundary.html Apart of being a very slow test, it is failing randomly in the Linux bot, together with a few other editing/selection slow tests: editing/selection/click-left-of-rtl-wrapping-text.html editing/selection/doubleclick-beside-cr-span.html editing/selection/hit-test-on-text-with-line-height.html editing/selection/rtl-move-selection-right-left.html
editing/selection/caret-at-bidi-boundary.html has been passing consistently for a long time, until we enabled threaded compositor. I'm reassigning it to bug #160119. Leaving this open to track the remaining failures.
This test(s) has been consistenly passing in the last 4000 revisions. Closing bug.
