Failures only occur on Apple Silicon Macs, and as such I cannot reproduce them because I do not have access to one. This test also appears to be flaky on Big Sur wk1 release Apple Silicon. Reproduced the issue on arm64 r279472: run-webkit-test --root --iterations 500 --exit-after-n-failures 2 imported/w3c/web-platform-tests/resource-timing/resource_timing.worker.html I was unable to determine regression point for this test after testing with multiple spades.

[ Monterey Release arm64 ] imported/w3c/web-platform-tests/resource-timing/resource_timing.worker.html is a flaky failure Description: imported/w3c/web-platform-tests/resource-timing/resource_timing.worker.html There was not one commit that I observed causing this issue. This test is flaky on Big Sur and Monterey Release wk1 and wk2. The first failure that I saw on the dashboard was 3/17/2022 at r291447, but this does not appear relevant to causing this issue.
