I just tested this on my HPE 1920-48G, and it works. But I'm running a 
build with some patches, so that may be the reason.

You could try if the changes from my multicast-snooping branch [1] fix 
the issue. One of them fixes an issue that can occur even without 
multicast snooping enabled and results in corruption of the unknown 
multicast port mask.

Best,
Jan
