Using bucket on cow while crouching won't allow drinking the milk

Using a bucket on a cow to get milk WHILE CROUCHING actually gives you the milk but trying to drink it will result in an endless animation until the right mouse button is released, this can be repeated multiple times but the milk won't be consumed and the potion effects will remain. Dropping (or moving in the inventory) the milk bucket will drop (or replace it with) an empty bucket.

Not sure if it's only my problem or not, but here are all the passages:

-press SHIFT to crouch

-while crouching, get the milk with an empty bucket from the cow

-not crouching anymore, try drinking milk

• if this resulted in endless animation, try dropping the bucket of milk, it will drop an empty bucket instead
