Pick Block on Head with Skullowner only gets Head Block

After I use NBEdit or MCEdit to add a skullowner tag to a head, when I use pick block on the head, I don't receive the skull with the skullowner tag with it. I only receive the head.

Steps on repeating the process:
1) Use MCEdit filter or use NBEdit tag editing to assign a SkullOwner to a head.
2) Place it down in your world.
3) Use the creative mode's pick block feature on the player head
4) You should only receive a regular head block instead of a head block with the skullowner data.
