For example, these results from the flakiness dashboard: <http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Ftext%2Femphasis-combined-text.html> This is the consequence of r126219 moving results from mac to mac-lion, which is not on the fallback path for LINUX or WIN. Similar changes (beidson@apple.com, mention "Rebaseline various tests for Mountain Lion" etc.) should be reviewed to see if they resulted in Chromium missing results.
Tried to restore one result moved in r126219 in r126266.
Marked LayoutTest bugs, bugs with Chromium IDs, and some others as WontFix. Test failure bugs still are trackable via TestExpectations or disabled unit tests.
