Bug 239634

Description: media/modern-media-controls/tracks-support/text-track-selected-via-media-api.html The first failure that I saw on the dashboard was 3/18/2022 at r291467, with the next not until 3/28/2022 at r292014 on Big Sur. The first failure that I saw on the dashboard was 3/29/2022 at r292056 on Monterey. The regression point could possibly be 267467-267466, although I was unable to reproduce it. The failures for Big Sur arm64 continue after that commit range and then continue with Monterey arm64.
