The following layout test is failing on chromium Mac10.6(dbg) and Mac10.8. Failure on 10.6 looks temporal, but it continues to fail on 10.8. fast/multicol/seamless-flowed-through-columns.html Probable cause: Result images are different a bit. It cannot be rebaselined because it is Reftests.
It starts to fail between r143179 and r143291. http://trac.webkit.org/log/?verbose=on&rev=143291&stop_rev=143179
The test is intoroduced at r143256
Update TestExpectations at r143315 morrita@, could you assign proper person to this issue?
