REPRODUCTION:
I was able to reproduce the failure on macOS Tahoe release ToT with the following:

run-webkit-tests  --no-retry --force —release --iterations 500 imported/w3c/web-platform-tests/media-source/mediasource-config-change-webm-av-video-bitrate.html

I am going to mark expectations as a pass fail while this pends investigation.
