Describe the issue
When the pitch is wrapped around when going inverted, the player hand suddenly moves slightly to use new pitch values.

Additional information
You could probably fix this by modifying the prev pitch value somewhere to something out of bounds, I haven't the chance to look.

Seems you have done this for yaw in ElytraMath

This seems like it'll require some complex math. :dies:

Is this fixed

Not really, haven't bothered to dig into it too deeply, as its a minor issue.
