The fast/multicol/newmulticol/column-rules-fixed-height.html reftest is failing since it's been introduced in r143395. http://trac.webkit.org/changeset/143395 The difference is minimal, one pixel or so. There's already a similar failure somewhere around, might as well call it a dupe. file:///dvt/webkit/webkit/Tools/TestResultServer/static-dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&tests=fast%2Fmulticol%2Fnewmulticol%2Fcolumn-rules-fixed-height.html
The column-rules-fixed-height.html test started to pass in r143467, so the TestExpectations change (-> expect to fail) in r143445 should be backed out.
Thanks for pointing it out, removed the expectation in r144284. http://trac.webkit.org/changeset/144284
