FYI, Discourse is suddenly having this problem as well on Chrome+MacOS so it may be a browser problem

(we haven't investigated yet)

@Supermathie did you ever figure out what the issue was? I was also seeing this in the Immich app, but they fixed it somehow - immich-app/immich#13519

Nope, I'm not really touching it after triage.

We did note that it seems to be consistently playing upside-down in Chrome and upside-up in Safari, so it's probably a Chrome problem.
