media/media-fullscreen-pause-inline.html

this test is a very infrequent flaky failure. I am able to reproduce this using 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 media/media-fullscreen-pause-inline.html
