Is fast/reflections/reflection-overflow-hidden.html the test that crashed? If so, it seems unlikely that a change to RenderTextTrackCue.cpp could cause that.

I saw that track-cue-snap-to-lines-not-set was failing and I thought that's one
of the failing tests mentioned, but looking again at the Chromium Mac10.6 it seems
like that the test is still failing anyway (weird output, though).

I think this was an unnecessary rollback.

I will be happy to r+ https://bugs.webkit.org/show_bug.cgi?id=110703 again if you have some time to watch the bots after it lands.

Sound good - I re-uploaded the patch and I'll watch the bots after
it lands.
