Drowned's Helmets Render Glitch inside Skull

Steps to Reproduce:

1.Set the difficulty difficult to ensure that drowned can pick up items.

2.Set the time night to avoid burning.

3.Drop a gold helmet on the floor.

4.Spawn a drowned. If the drowned cannot pick up the helmet and wear it on, kill it and spawn another until one can.

Phenomenon:

Helmet is inside skull. There are some gold spots on drowned's head.

Expected Results:

The helmet can fully render like Java Edition.

 

It relates to MCPE-119989, but this render problem doesn't need conversion from zombie.

There is nothing to do with MCPE-74242, because it didn't mention drowned.
