Firefox extension break website rending

Hello
When I go to the page :

and try the first demo/play code…
=> The preview / result of the code don’t show up…
… But works when I disable Bitwarden extension…

To find the bug

I try Troubleshoot mod (disable extensions)
=> works !

I reactivate all of extensions one by one
When Bitwarden extension is ON
=> cant see planet animation anymore…

Why ?
Thanks

When I test it, I can see the preview animation on the main page (https://developer.mozilla.org/fr/docs/Web/API/Canvas_API/Tutorial/Basic_animations), but I can reproduce the issue on the page that is launched when clicking < /:arrow_forward: Play (https://developer.mozilla.org/fr/play). For me, the issue seen on the “Play” page is resolved if I disable “Ask to save and use passkeys” under Settings > Notifications in the Bitwarden browser extension.

For what it’s worth - I had the same issue on a local grocer’s website. Unchecking “Ask to save and use passkeys” resolved it.
