When spears left-clicking while switching to another item, the item'll show the spear stab animation

As I know, this is an issue at least showed up at 26.3-sanpshot-6, as switching the spear that is playing animation to another item, this item will also show the animation of the slab of spears.

Steps to reproduce the issue

Choose a spear and change to another slot with any item when it is playing animation

Expected result

Item will not play animation

Actual result

Item will play animation
