Desync when a player rides a horse riding another mob, and that mob dies

If a horse is riding a mob, and that mob gets killed, players riding that horse get kicked off the horse client-side but not server-side.

To reproduce

1. Run the following command:

   /summon husk ~ ~ ~ {Passengers:[{id:"minecraft:horse",Tame:1b}]}

2. Place a block of TNT next to the husk

3. Ignite that TNT

4. Mount the horse

5. When the husk dies, you get dismounted

6. Walk away

7. Sneak
   → ❌ You get teleported back to the horse
