css3/flexbox/content-height-with-scrollbars.html from https://bugs.webkit.org/show_bug.cgi?id=92667 is failing image comparison (just!) on Lion and Mountain Lion.
Expectations in http://trac.webkit.org/changeset/125093
Looks like it's failing on GTK as well: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&tests=css3%2Fflexbox%2Fcontent-height-with-scrollbars.html. Looks like a rounding error. I would guess that this works in Chromium because we have sub-pixel layout enabled. Although, that doesn't explain why it's not failing for Qt/Efl.

I would guess that this works in Chromium because we have sub-pixel layout enabled. Although, that doesn't explain why it's not failing for Qt/Efl. Maybe Qt and Efl have scrollbars that are an even number of pixels, allowing the rounding to work? I'll see if I can change the test so it'll work on all platforms.
Fixed the test in http://trac.webkit.org/changeset/125140 .
