Comment 1 Bri Harris 2023-02-27 15:27:00 PST

I was able to replicate this failure at iOS 16 ToT as follows:

run-webkit-tests media/track/track-description-cue.html
run-webkit-tests media/track/track-extended-descriptions.html


I was also able to reproduce this failure on build of 260774@main but not at 260771@main. With the first failure showing on 260775@main, it narrows down our range of regression to 260772@main - 260774@main.
