The following layout test (it's reftest) is failing on chromium Mountain Lion. fast/regions/region-style-in-columns.html Dashboard: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Fregions%2Fregion-style-in-columns.html Probable cause: http://trac.webkit.org/changeset/144633 It seems it started to fail after r144633. Diff of images looks very litte. If It's not a reftest, I'd just rebase it. Hmm..
Marked as [ImageOnlyFailure] on chromium's TestExpectations. http://trac.webkit.org/changeset/144868
Works for me on today's nightly (r151543)
Reopening - we'd like to know when it got fixed and how. If it's a Blink-only bug, we'll migrate it in their bug-base.
