Middle mouse button doesn't give specific heads, just "player head"

Using middle mouse button to get an item in your inventory gifts you that said item. However if this is used on a player head, say names "Links" instead of giving you "Links's Head" you are given "Player's Head" the default steve skull. It's obnoxious to have to re-enter the name later if I want to move the skull as well as forgetting what the head was named.
