Baby Zombies, Husks, Drowned, Zombie Villagers, Piglins, and Zombified Piglins holds extremely oversized items that often clips into the ground or with an item in the off hand.

Previously in 1.21.11 when hostile Baby mobs hold items or weapons, they will be shrunken down to fit the size of the baby model. However with the re-models this is no longer the case, resulting in various cases of clipping.

How to reproduce:

1. Use these commands to summon a baby mob holding some items.

/summon zombie ~ ~1 ~ {IsBaby:1,PersistenceRequired:1,equipment:{mainhand:{count:1,id:birch_planks},offhand:{count:1,id:stone}}}

/summon drowned ~ ~1 ~ {IsBaby:1,PersistenceRequired:1,equipment:{offhand:{count:1,id:shield}}}

/summon zombie_villager ~ ~1 ~ {IsBaby:1,PersistenceRequired:1,equipment:{mainhand:{count:1,id:trident}}}

/summon zombified_piglin ~ ~1 ~ {IsBaby:1,PersistenceRequired:1,equipment:{mainhand:{count:1,id:golden_spear}}}

/summon piglin ~ ~1 ~ {IsBaby:1,IsImmuneToZombification:1,PersistenceRequired:1,equipment:{mainhand:{count:1,id:crossbow}}}

/summon husk ~ ~1 ~ {IsBaby:1,PersistenceRequired:1,equipment:{mainhand:{count:1,id:mace}}}

1. Go into spectator mode

2. move just below the ground to view how much certain items clips into the ground.

Expected Result: The items in these baby mobs hands should shrink down to fit their model sizes.

Actual Result: The items remains very large and often causes them to clip into the ground.
