Donkey head gets stuck lowered if mounted during head-lowering animation

If a player mounts a tamed and saddled donkey exactly when it starts lowering its head toward the ground, the donkey’s head gets stuck in the lowered position.

The head only returns to normal after the player dismounts.

Steps to Reproduce:

Tame a donkey and place a saddle on it

Wait for it to start lowering its head toward the ground

Mount the donkey during the animation

The donkey’s head gets stuck lowered

Expected Result:

The donkey should return its head to the normal position after the animation.

Actual Result:

The donkey’s head remains lowered until the player gets off the donkey.
