--- Comment #3 from Brion Vibber <bvibber at wikimedia.org> ---
This affects video codecs as well as audio; canPlayType() reports '' for 'video/webm; codecs="vp8"' and 'video/webm; codecs="vp9"' even if they play back just fine in <video>.

Same behavior on TP 131 and the current beta of Monterey.

This is a hard blocker for us being able to switch from WebAssembly decoding to native playback of WebM video on Wikipedia.
