[GAMEPLAY] Jarvan IV- Passive Bug when Autoattacking

On Jarvan, when auto-attacking(anything) the first hit that would proc his passive freezes him mid animation, standing, running, or what not. You then have to reclick to start attacking again after a pause, and your passive damage doesn't apply.

To recreate this (you just have to been unlucky enough to get the bug) -auto-attack anything -Freeze

Important note thought, this doesn't happen in every Jarvan game, idk why, but it is painfully obvious when it does. It has happened to me 2 out of 5 games, not in a row, and over a long period of time. The last time it happened was in a ranked game and didn't allow me to contribute to the team much, hard to teamfight when your freezing every time you attack a new target. Anyway that's what I know see the video below for a clear example, the bug happens a 2seconds and 5seconds. The video is not the best because I was trying to jg and tape it and the same time so I apologize also please ignore the music. Thanks for taking the time to look and this, and post if you have any problems viewing the video and I'll try to fix them.
