If you attemt an backflip with the elytra, the game crashes

1. Take Elytra Wings
2. Take Firework rocket(at least the ones with flight duration 1)
3.Boost the Elytra
4.Fly up and try a looping backwards
5.When you are just about straight up, the game crashes and says "invalid Player movement package recieved" and takes you back to the server list(I was in Singleplayer)
