As I was searching my inventory, I noticed that the chain command blocks behind my character in my inventory were showing through the enchanted armor and shield.

Observed Results:
Blocks are appearing through.

Expected Results:
Nothing should appear through.

Steps to reproduce:
1) Equip any form of enchanted armor, or enchanted shield in the offhand slot.
2) Stand behind chain command blocks (unknown if it works for other blocks).
3) The chain command blocks should be visible where they and the enchanted armor overlap.
