Description Karl Rackler 2022-05-27 15:36:46 PDT

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