Subject: [PATCH] MC-111699: Ignore Improper Anvil Item Name Packets
The client is improperly sending Item Name Packets to the server BEFORE
the click event. This causes the server to reset before the click event is processed
This breaks the ability to rename more than 1 item at a time.
See: https://bugs.mojang.com/browse/MC-111699
