The switch keeps flooding 224.0.0.0/24 with IGMP on, but a report for a group in that block still made an entry for it, and the entry limited the group to the ports that reported it. A host announcing mDNS on 224.0.0.251 thereby cut mDNS off from every other port. Such reports are now ignored, as RFC 4541 asks.
