Heads are not in hand when in both Third-Person views (Even in Survival Inventory)

when i go to third person mode (rear & frontal view),
and get all 5 heads I saw that the heads aren't on my hand.

EDIT: This can also be seen in the inventory

How to see it:
1. Go to creative mode
2. Get any kind of head items (Steve, Skeleton, Creeper, Wither Skeleton, Zombie)
3. Go in to Third person mode (frontal view or rear view)
4(optional).Go to survival if you placed a head in creative mode, break it
4(continued).Go to the inventory, you will see the glitch.
