Created attachment 465201 [details] Image Diffs fast/mediastream/MediaStream-video-element-video-tracks-disabled.html is a constant failure on iOS 16. HISTORY: https://results.webkit.org/?suite=layout-tests&test=fast%2Fmediastream%2FMediaStream-video-element-video-tracks-disabled.html IMAGE DIFF LINK: https://build.webkit.org/results/Apple-iOS-16-Simulator-Release-arm64-WK2-Tests/260882@main%20(1004)/fast/mediastream/MediaStream-video-element-video-tracks-disabled-diffs.html Also included zip file of images.
I was able to replicate twos failure on iOS 16 ToT as follows: run-webkit-tests fast/mediastream/MediaStream-video-element-video-tracks-disabled.html I was able to replicate this failure on builds as early as 260575@main but not at 260574@main and later, where it is passing. This appears to be the regression point.
