The player head second layer isn't is the correct place.

I was surprised to find that this bug has been around before Christmas, yet it doesn't seem to be fixed nor reported yet even though I know many have been experiencing it.

 

The second layer of player head item is below the actual player head in inventories and when on the ground.

Here is an example and evidence may have this issue: https://www.reddit.com/r/Minecraft/comments/a8x6zn/the_114_snapshots_have_a_player_head_glitch_that/
