If you freeze the game with /tick freeze and try to make a camel you are riding stand by pressing a direction, the camel visually stands but the player stays where they are. The camel is also not controllable.

Reproduction Steps:

1. Spawn a camel and equip it with a saddle
2. Wait for the camel to sit
3. Freeze the game with /tick freeze
4. Ride the camel
5. Press one of WASD

You will see the camel visually get up but your player is still sitting where you were originally.

I don't know if this would technically be considered a bug because the game is frozen, but at the same time entities you are riding are supposed to not be frozen. I'm not sure if riding a sitting camel counts as "riding" it (in the context of a frozen game) and should unfreeze it (and properly stand up and reposition the player).
