Steps to reproduce:

1. Spawn a baby zombie with the ability to ride mobs enabled.

2. Place a horse, donkey, mule, zombie horse, or skeleton horse nearby.

3. Allow the baby zombie to mount the mob.

4. Stand directly in front of the mounted baby zombie and observe its attack behavior.

Observed result:
The baby zombie is unable to attack the player consistently while mounted. Moving around the mob further demonstrates the issue, as the baby zombie becomes easy to avoid and kill due to the large size of the horse-type mob compared to the zombie’s attack range.

Expected result:
The mounted baby zombie should be able to attack the player consistently damage the player.

The same problem occurs with

Donkeys, Mules, Zombie horses, and Skeleton horses if a zombie, husk, drowned, or zombie villager is riding them.
