This test is a flaky failure on macOS wk2.

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=webrtc%2Fvp8-then-h264-gpu-process-crash.html&platform=mac

TEXT DIFF:

 PASS Setting video exchange with VP8
 PASS Setting exchange with H264 using VP8 decoded stream as input
-PASS Frames should be coming even after gpu process crash
+FAIL Frames should be coming even after gpu process crash promise_test: Unhandled rejection with value: "test increasing frame decoded timed out"

DIFF URL:

REPRODUCIBILITY:

I was able to reproduce this bug on macOS Ventura (13.5, 22G74/arm64) using the following command:

rwt --clobber-old-results --verbose --iterations 500 --child-processes 10 -f --exit-after-n-failures 1 webrtc/vp8-then-h264-gpu-process-crash.html

REGRESSION:

The regression point seems to be 267620@main, as this was the first instance of the failure and the changes appear directly related to the failing test.

This appears to have stopped flakily failing around the time https://commits.webkit.org/269258@main landed. We should remove the flaky expectation.
