I was not able to reproduce the timeout after being able to reproducing at tip-of-tree  one time using run-webkit-tests media/modern-media-controls/scrubber-support/scrubber-support-drag.html -1 -f --iterations 500 --exit-after-n-failures 2 --exit-after-n-crashes-or-timeouts 2 --no-build

The flaky timeout is still happening. I still cannot reproduce the timeout with wk1, but with wk2 I was able to reproduce the timeout using run-webkit-tests --iterations 100 --force --exit-after-n-failures 1 --debug media/modern-media-controls/scrubber-support/scrubber-support-drag.html

The test timed out with the same diff on r272842 and passed on r272841.

It looks like this times out rarely on WK1, but it is very frequently timing out on WK2. Adjusting title.
