The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

:emilio, since you are the author of the regressor, bug 1891063, could you take a look? Also, could you set the severity field?
