[BugBot [:suhaib / :marco/ :calixte]]

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.

A lot of sites are using animated images in place of ads these days to get around autoplay settings. This might be one of those cases.

I tried to take logs couple times, but every time it wasn’t reproducible

It still reproducible intermittently, once in dozen YouTube’s
Last time it was in embedded YouTube opened inside Google search results
