[MC-97696] Mobs in minecarts will not be posistioned correctly when going into unloaded chunks

When a mob is in a minecart and travels into unloaded chunks the mob is not rendered in the minecart but standing on the rails. You can not interact with them on the track and will float when the blocks are broken beneath them and the minecart will continue on the rail. If you try to hit the mob as if they were in the minecart they will not take any damage but they will take damage when shot at with an bow and arrow or suffocating in a block. When the minecart is broken the mob will teleport to the minecarts position.

At least related to MC-96954.

Are error messages described in MC-90683 in your Game Output?

Same problame in Minecraft 1.9.2

Confirm for 1.9.3 pre-2 and I get this warning message in the Game Output [Client thread/WARN]: Received passengers for unknown entity

I cannot confirm the game output in 1.10, and everything else is just MC-96954.
The issue with the game output is described in MC-90683 and might happen if there is for instance an end crystal in your minecart, or another entity that has a higher render distance then minecarts.
