When you use a bundle to take out items, hand animation is always played on main hand, not the hand holding the bundle. This does not occur in 1.21.3.

Steps to reproduce:

1. Put any items in a bundle on your main hand and right click
2. Hand animation is played on main hand
3. Repeat 1, but the bundle on off hand
4. Hand animation is played on main hand, not off hand

This issue occurs regardless of whether your main hand is right hand or left.
