Loaded crossbow in offhand causes main hand(if empty) to render weirdly

A loaded crossbow in offhand would cause the (empty) mainhand to render tilted to the left, when punching, the main hand would render normally for a frame and play the hit animation and the go back to the tilted position again.

Steps to recreate:

1.create a world.

2.obtain a crossbow and put it in the offhand slot.

3.charge the crossbow with the main hand empty.
