The saddles of some entities stay visible through their death animation

Although horse armor, carpets, and chests now visually disappear during an entity's death animation, the saddle on horses, donkeys, mules, zombie horses, skeleton horses, and camels still remains visible.

Affected Mobs:

1. Horse (zombie and skeleton too)

2. Donkey

3. Mule

4. Camel

Steps to Reproduce:

1. Summon one of the affected mobs

2. Put a saddle on it

3. Kill the entity

Observed:

The saddle item that was equipped on the entity will be visible in air/on the ground, while the saddle on the entity is also still present.

Expected:

Because the saddle item is present inside the game space, the saddle on the entity would be removed before the death animation plays, avoiding visual item 'duplication'.
