I was able to reproduce the text failure locally on my device running iOS 18 Simulator Release ToT using the following command:

run-webkit-tests http/wpt/mediarecorder/MediaRecorder-matroska-AV-audio-video-dataavailable.html --ios-simulator -iterations=10

It looks like this test has been flakily failing since it has been introduced. It is a bit tough to pin point an exact regression point.
