same issue here on my SMP server
currently looking forward to a fix 👀

Happens on my server. Im using multiverse + multiverse inventories, world border. Worlds "spawn" and "survival" have separated inventories.

1. Player logs out while mounted on a horse/donkey on "survival" world with coordinates {x,y,z}
2. Connects again to the server on "spawn" world - in location where registered players type /login
3. After logging in Player is teleported to the same {x,y,z} coordinates on the "spawn" world. With the horse/donkey even though i have world border set
4. Player gets instantly teleported to the world he logged out of (in this case "survival"). The horse/donkey is left behind in the "spawn" world. Player ususally cannot move, or suffocates inside walls. He looks as if he was standing, without the horse,
5. After Player leaves and rejoins server he can move. Paper removes duplicate entity with the same UUID as if the horse was in both worlds? I dont know really.

So basically player either dies or cannot move, his horse/ donkey with items in chest is either stuck in spawn world, or gone completely.
