This seems to be due to the same root cause as #120283 which has already been resolved. This test doesn't seem to be muted anymore either. I'll double check with Jan who fixed the root cause and then can resolve this if there is no further action required.

[jan-elastic]

Yes, that's the same issue. My backport PR got merged a few hours after this report, so it should be fixed. Closing this one...
