Skullowner is lost when "picking" the skull in creative

When you pick a skull with skullowner (and you dont have any other heads in your inventory) you'll get a normal head without its owner.
If you have one or more heads in your inventory, with or without skullowner, and you pick any skull, the first one will be selected. And if none of them are in your hotbar, one will be moved to there and it will lost its owner.

What i expected: get always the head that i pick
