Animation bug with Slayer Jinx's AAs with Pow Pow the minigun.

I've noticed that not only in spectator mode, but also in a live game, that Slayer Jinx's AAs while using her Minigun are messed up. The animation goes to that which she has targeted, and then the AA pauses for around 0.5 seconds. Immediately afterwards it just disappears. I would take a screenshot but a picture obviously wouldn't actually capture this, and I don't know how to take video. Sorry!
