Summary:

There is a missing function with some item's animations.

Steps to reproduce:

1. Pick a bow, a trident, a crossbow, a shield, a spyglass and any other item (Example: any sword).

2. In the first person view, slowly switch between those items, and than the sword.

---> You will see that the sword have an animation which she moves in the screen, likely simulating the animation where the player holds any item in third person view.

Observed Results:

the trident, bow, crossbow, shield and the spyglasses are completely froze in the first person view screen, making no animations.

Expected Results:

Like the sword, all those items should have the "item moving in the screen" animation.

I also uploaded a video to make it easier to see the bug.
