Yes, it sounds like a symptom of the same issue, in which case the patch there should have fixed it.

joaobzzr, can you try this with Firefox Beta (v.123) or Nightly (v.124)?

Indeed this seems to be fixed on Firefox Beta (v.123).

Great, thanks for confirming that! Let's resolve this as a dupe of bug 1873708, then.
