I was able to reproduce this issue at Monterey production ToT by running: run-webkit-tests media/media-source/media-webm-vorbis-partial.html I was not able to narrow down the regression to a specific build due to not having sufficient builds available to test on within the regression range. However, I was able to narrow down possible commits that may have caused the issue to three separate commits: https://commits.webkit.org/251565@main https://commits.webkit.org/251570@main https://commits.webkit.org/251568@main
