On a multiplayer server, if I disconnect from and reconnect to the server while riding a vehicle (have tested horse, boat, minecart) the client dismounts the vehicle but the server still thinks I'm riding it.

Other players see me in the vehicle while I can move around freely. I can't break or place blocks or interact with anything in the world but I can walk to the edge of the map and fall into the void (taking no damage) because the server doesn't load chunks around me as it thinks I'm still in the vehicle. Pressing shift triggers the server to dismount me so I teleport back to the vehicle and can then play as normal.

This seems to be similar to MC-191714 and MC-202202 but triggered in a different way.
