The following layout test is failing on Chromium-Lion: fast/css/nested-rounded-corners.html http://test-results.appspot.com/dashboards/flakiness_dashboard.html#showExpectations=true&tests=fast%2Fcss%2Fnested-rounded-corners.html Seems like scrollbar is not painted on Lion.
looks like this is no longer failing? removing the suppression in http://trac.webkit.org/changeset/128950
