Player heads attached to walls don't show in xray

[dmdinnc]

Describe the bug
When using the xray on player heads, heads not sitting on the ground are not counted. This is likely due to it technically being a different item.

To Reproduce
Steps to reproduce the behavior:

1. Set xray to find player head
2. Attach a player head to a wall

Expected behavior
Show heads that are on walls, since it's still a block, albeit with a different ID
