Description:
fast/canvas/canvas-createPattern-video-loading.html

The first timeout I saw on the dashboard was on 5/24/2022 at 250916@main.  This appears to have regressed in the 250916@main-250910@main range.  At 250910@main, the fast/canvas/canvas-createPattern-video-loading.html test was re-written using requestVideoCallbackFrame, and this is most likely the cause for the start of the flaky timeouts at that same timeframe.

REPRODUCTION STEPS
I can reproduce this on 250910@main.

Command: 
run-webkit-tests --debug -1 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --iterations 50 -f --no-retry fast/canvas/canvas-createPattern-video-loading.html

Result: 
Unexpected flakiness: timeouts (1)
  fast/canvas/canvas-createPattern-video-loading.html [ Pass Timeout ]

I have marked this test as a flaky timeout/crash while this issue is investigated.
