After 305168@main, http/tests/webgpu/webgpu/web_platform/copyToTexture/video.html started failing. Seems likely to be a rebaseline. History: https://results.webkit.org/?suite=layout-tests&test=http/tests/webgpu/webgpu/web_platform/copyToTexture/video.html Build: https://build.webkit.org/#/builders/1716/builds/1009

Based on the history link, it looks like this started failing with https://commits.webkit.org/304987@main, no?

I don't see the test having failed on the PR for that commit, but it looks like the whole directory is marked as flaky so it isn't running on EWS (due to the --skip-failing-tests argument) LayoutTests/platform/mac-wk2/TestExpectations:2364:http/tests/webgpu/webgpu/web_platform/copyToTexture [ Pass Timeout ]

Yes, regression point is https://commits.webkit.org/304987@main, I fat-fingered the commit in the original report.
