Riding an entity into portals may cause the game to softlock
Another discovery is it might teleport you to the void and cause softlock(You don't take fall damage)
Reported as MC-272329.
More tests:
This bug happens mostly when teleporting from nether to overworld. (In some situations, overworld to nether, overworld to the end, the end to overworld also happens)
When you riding an entity and teleport from nether to overworld, you will be teleport correctly, but the horse will teleport to the same place in the nether, if the distance from your place in overworld and the horse is close, you will be teleport to the horse, cause this bug.
If the distance from your place in overworld and the horse is far(the horse is in unloaded chunk), it will cause a huge desync from client and server, and your game will be softlock, you can't break blocks in survival, and even if you fall into the void, you won't take any damage. The server maybe freeze in this situation(That's MC-272329) When you quit and relog, you will be teleported to the horse.
I can confirm some of this. The game seems to softlock when entering a nether portal on horseback (step 4). I could save the game, and when I loaded the game again I was back in the Overworld and there was no Nether portal.
Edited to add: On reload, the horse was also in the Overworld and the player was riding it. Player and horse ended up in an ocean. I used seed 1 for the world.
I can confirm too.
