After r126534, the ref-test fails on Win. It looks like we are displaying seconds on Win but not on other platforms: http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Fforms%2Ftime-multiple-fields%2Ftime-multiple-fields-appearance-pseudo-elements.html I will disable the ref-test on Win for now.
r126736 obviated the expectation linked to this bug, but I believe the bug may still be valid. For now I am removing the expectation to unbreak run_webkit_tests.py --lint-test-files --chromium.
I did rebaseline (http://trac.webkit.org/changeset/126843)
