The Bug:

The rearing animations of horses, donkeys, and mules sometimes aren't displayed for other players.

When a player jumps while riding a horse, donkey, or mule, the player who's riding the entity will always be able to see it rearing, but for other players, they are only able to occasionally witness this animation play.

Steps to Reproduce:

1. Summon a horse with a saddle equipped on it by using the command provided below.

   /summon minecraft:horse ~ ~ ~ {Tame:1b,SaddleItem:{id:"minecraft:saddle",Count:1b}}

2. Get two players and label them "Player A" and "Player B".
3. Get "Player A" to mount the horse and have "Player B" watch them.
4. Get "Player A" to jump quickly while riding the horse several times.
5. Take note as to whether or not the rearing animations of horses, donkeys, and mules sometimes aren't displayed for other players.

Observed Behavior:

An animation sometimes isn't displayed for other players.

Expected Behavior:

An animation would always be displayed for other players.
