fast/layers/no-clipping-overflow-hidden-added-after-transform.html is flaky on mac-wk1 http://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=fast%2Flayers%2Fno-clipping-overflow-hidden-added-after-transform.html Seems to have started with https://trac.webkit.org/r200047
Is there a concrete reason to not roll out?
This is happening because of this change: http://trac.webkit.org/changeset/200047/trunk/Source/WebCore/page/animation/AnimationBase.h When the transitionEnd event fires, we no longer treat the animation as running, so we drop out of compositing earlier. I don't think this change justifies a rollout, but I'll keep this bug to determine if it needs fixing.
