media/video-fullscreen-only-playback.html

This test appears to have become flaky with the changes in r263121.  We were able to reproduce this with this command:
run-webkit-tests --iterations 2000 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --debug-rwt-logging --no-retry --force --no-build -f --debug  media/video-fullscreen-only-playback.html
