imported/w3c/web-platform-tests/webaudio/the-audio-api/the-audiobuffersourcenode-interface/audiobuffersource-duration-loop.html

Is a flaky failure on Big Sur E wk1 Debug.

History: https://results.webkit.org/?suite=layout-tests&test=imported%2Fw3c%2Fweb-platform-tests%2Fwebaudio%2Fthe-audio-api%2Fthe-audiobuffersourcenode-interface%2Faudiobuffersource-duration-loop.html

I was not able to reproduce the failure, but instead the test timed out on my local intel machine using:

run-webkit-tests imported/w3c/web-platform-tests/webaudio/the-audio-api/the-audiobuffersourcenode-interface/audiobuffersource-duration-loop.html --iterations 500 -f -1 --exit-after-n-failures 2 --debug

run-webkit-tests imported/w3c/web-platform-tests/webaudio/the-audio-api/the-audiobuffersourcenode-interface/audiobuffersource-duration-loop.html --iterations 50 -f -1 --exit-after-n-failures 2 --child-process 1 --debug
