compositing/video/video-border-radius.html frequently times out on Mountain Lion only (all bots). The test is very simple, so it's quite a mystery.
Skipped the test on <http://trac.webkit.org/r176022>. Looks like multiple tests in compositing/video time out on Mountain Lion only.
We only have one platform expectation for this and it is on Mac-wk1 and it is tracked in separate bug: https://searchfox.org/wubkat/source/LayoutTests/platform/mac-wk1/TestExpectations#2378 webkit.org/b/241266 compositing/video/video-border-radius.html [ Pass Timeout ] Marking this as 'RESOLVED CONFIGURATION CHANGED'.
