Using a wind charge and swapping it at the same time produces fake usage animation

When you use a wind charge and swap it at the same time (or with minimal delay), the wind charge isn't created, but the item in your hotbar visually displays a cooldown animation, and the item count decreases for a couple of frames and then returns back (attachment 1). This is a fake cooldown, as you are still able to use the wind charge during that animation (attachment 2).

_{Noticed this when I was trying to learn the new PvP tricks with the new items, quite annoying bug.}
