The harness layer is not scaled correctly on baby happy ghasts

The Bug

Baby Happy Ghast doesn’t render harness layer in a correct scale.

Reproduce

1. Spawn a Happy Ghast using Spawn Egg.

2. Grab any harness and then put it to a Happy Ghast.

3. Use command to set Happy Ghast to baby

   /data modify entity @n[type=minecraft:happy_ghast] Age set value -24000

4. Use /tick freeze command then switch to spectator gamemode.

5. Look inside the baby happy ghast that equipped a harness.

Observed Behavior

Baby Happy Ghast harness rendered inside the entity.

Expected Behavior

Baby Happy Ghast should render harness on a proper scale.

Fix

I have attached fix code to make it render properly. Just simply remove baby argument and remove apply part with the BABY_TRANSFORMER in the HappyGhastHarnessModel class.
