Description:
This test is a flaky failure on Mac WK2. It is a known constant failure on Catalina wk1 from webkit.org/b/205226
The diff shows a 1 when it should be a 4 with a lesser blue curve on the left side.
I am able to reproduce this locally by just running this test in iterations. 
It looks like this started around r252246 which is the earliest failure.

    <thetext>results.webkit.org shows a clear regression in early November, but internal bots have been flakily failing throughout the history.

Why is this test that is about clipping so flaky? Can we just have a video whose frames are all the same perhaps?</thetext>

    <thetext>It&apos;s flakey because it&apos;s apparently impossible to have a non-flakey test that actually shows video frames.</thetext>
