[MCPE-201778] Happy Ghast becomes fully black when one block is above it

Expected behavior

The happy ghast doesn’t turn into a solid black colour.

Steps to reproduce

Grow happy ghast
Put harness on happy ghast
Ride happy ghast and park it on the floor
Put blocks on top of happy ghast until the mob turns black (/setblock ~ ~ ~ stone)
Remove remaining blocks to make it look weirder I guess.

This tends to happen only at the center of the happy ghast.

Can Confirm

Still works as of latest snapshot.

That’s normal, when it’s INSIDE the ghast. WTF?!

Visually the block is not inside the ghast nor is the ghasts position inside of the block. Just some hitbox extends farther than it should.
