When you right click and swipe down/up very fast the barrel will do the open animation and it will stay opened till you open it, then it will close. 

Expected result

Barrel would not do animation when swiping very fast well right clicking

Actual result

Barrel will open and stay open when swiping very fast well right clicking and the only way to stop this is by opening the barrel normally

How to reproduce

1. Get a barrel and right click very fast
2. Swipe down/up very fast and you will see the barrel animation and the barrel will stay open

Even though its a small bug its still a bug. Not being mean
