If you move the screen and open the inventory the screen keeps rotating, allowing a weird glitched view. Sorry for not including a picture, I took a screen shot and I could not find it.

I expected the screen movement to be blocked after a certain rotation.

The screen continued to rotate, allowing an upsidedown view inside of the inventory screen.

Steps to Reproduce:
1. Tame a horse and ride it.
2. Start making the screen rotate towards the bottom, as if you were looking at the horse
3. open the inventory while still moving screen, it will keep rotating allowing you to see the game upsidedown inside of your inventory.
