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:
Put any items in a bundle on your main hand and right click
✔ Hand animation is played on main hand
Repeat 1, but the bundle on off hand
❌ Hand animation is played on main hand, not off hand
This issue occurs regardless of whether your main hand is right hand or left.
I am able to reproduce the reported behavior. It was introduced in 24w46a, presumably due to the fix of MC-277399.
