[1.12.2] Stop player rotation while riding

[Meldexun]

I made an entity which can be ridden. But when the player turns to the left or to the right to body of the player isn't fixed to the rotation of the head/entity which is ridden. How can i achieve that the body of a player is rotating the same. You can compare a Minecart and a Boat from vanilla. With a boat the rotation of the body of the player is fixed.

Override Entity#applyOrientationToEntity and do whatever you need to the player's rotation there.
