[Henrik Skupin [:whimboo][⌚️UTC+1]]

This started to fail by the wpt downstream sync for the new tests on bug 1874748 for Firefox 129. At this time we were not notified by the bot about that perma failure.

It needs further investigation.

Comment 4

[Alexandra Borovova [:Sasha]]

Looks like the test fails because we don't receive the browsingContext.userPromptOpened event, that looks like pretty much like the bug 1879324. I'll add the bug link to the metadata.
