Sample ImageDiff Output (texture-triangle-strip.diff.png)

The following layout tests are flaky failures as of the patch landed in r249460, which sought to resolve constant failures described in bug 201478, resulting from the patch landed in bug 201425:

webgpu/blend-color-triangle-strip.html
webgpu/blend-triangle-strip.html
webgpu/color-write-mask-triangle-strip.html
webgpu/depth-enabled-triangle-strip.html
webgpu/simple-triangle-strip.html
webgpu/texture-triangle-strip.html
webgpu/viewport-scissor-rect-triangle-strip.html

Steps to Reproduce:

The following tests are flakily timing out/failing when run in isolation. When run with other tests from the above list, these tests seem to cause otherwise passing tests to fail or timeout.

webgpu/blend-triangle-strip.html
webgpu/depth-enabled-triangle-strip.html
webgpu/texture-triangle-strip.html

run-webkit-tests --no-retry --no-sample-on-timeout --test-list triangleStripList --iter 10000 -f

Where triangleStripList is a text file containing at least 1 of the tests listed in 'Steps to Reproduce', and any other test(s) from the overarching list.

Attached sample ImageDiff output.
