There appears to have been a regression on this, as it doesn't seem to work in Firefox 101.0.1
I'm going by https://stackoverflow.com/a/69164082/6691 which mentions that it was fixed in version 92.

"it doesn't seem to work" is a bit vague, can you file a new bug with a test-case? Happy to take a look. Thank you.
