Mounted horse is not teleported to the same world as player after relogin

[Pawialdo]

What behaviour is observed?

If Player logs out while mounted on a horse/donkey their mount will not be with them after logging back in. From Players perspective their mount is lost where in fact its teleported to different world.

What behaviour is expected:

Players should log back in and have their horse with them no matter where they logged out.

Configuration:

    SaveQuitLocation: true
    teleportUnAuthedToSpawn: true

Rest is default. Spawn is set in world: World

Steps to reproduce:

1. Player is mounted on a horse/donkey in world: Nether (or any other than spawn world: World).
2. Player disconnects from the server.
3. Player connects to server and has to login in spawn location in world: World.
4. After Player logs in he is teleported back to world: Nether where he previously disconnected. Horse is teleported to the same coordinates but in world: World.

Plugin list:

AuthMe 5.6.0 build 2388, ProtocolLib Server engine : PaperSpigot 1.15.2 (latest build) I've reproduced this bug in isolated case with just these two plugins installed.

Error Log:

No error in console/logs

Same issue for me, happening to all rideable entities like boats and so on.

In 1.16.5 for me
