Description:

imported/w3c/web-platform-tests/html/canvas/element/manual/wide-gamut-canvas/canvas-display-p3-drawImage-video.html 

The first failure that I saw on the dashboard for Big Sur was on  2/15/2022 at r289815.  The first failure for Monterey was on 3/17/2022 at r291428. The first failure for iOS was on 12/21/2021 at r287308.   These tests have been flaky or consistent failures for their entire history on the dashboard.  iOS, Big Sur, and Monterey wk1 have been consistent failures.  Monterey wk1 is also a flaky timeout.  Monterey wk2 has been a flaky failure.  

REPRODUCTION STEPS
I can reproduce this on ToT.

Command: 
[ iOS ] consistent failure
ToT 294933
run-webkit-tests --ios-simulator --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --iterations 50 --no-retry --force --no-build imported/w3c/web-platform-tests/html/canvas/element/manual/wide-gamut-canvas/canvas-display-p3-drawImage-ImageBitmap-video.html

[ Monterey wk1 ] consistent failure or timeout
ToT 294943
Regressions: Unexpected timeouts (1)
run-webkit-tests --root 294943 -1 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --iterations 50 -f --no-retry imported/w3c/web-platform-tests/html/canvas/element/manual/wide-gamut-canvas/canvas-display-p3-drawImage-video.html

[ Monterey wk2 ] flaky failure
