So, basically, the view model and the view bobbing are very inaccurate to java editions, and it is also very buggy.

Solution for this:
Rewrite the view model or,
Manually fix the code
What's a view model?
The hand on the first person screen, that also displays items in 3d.

This has not been resolved since 1.13.0, this is getting kind of ridiculous..

Please make the bedrock hand and bobbing like java editions..
