Players' arms follow the position of sneaking players when holding loaded crossbows or fully charged bows

The Bug:

If you crouch while holding a loaded crossbow, the arms follow the position of the crouching/sneaking player. It also happens when a player is loading a crossbow. It also affects bows.

Steps to Reproduce:

1. Have a loaded crossbow
2. Crouch/sneak
   → The player arms follow the position of crouching while holding a loaded crossbow
