Braum glitches through air when interacting with Anivia wall

Hai :3 So I played Braum last game. Opponent had an Anivia. In the very last fight of the game, I was running away from river towards my team, but Anivia sets up her wall just as I use my W(Stand behind Braum) to jump to an ally(Vayne). So I basically end up floating around in the air - unable to move - unable to use skills. Gonna admit, it looked damn funny!! A floating man carrying a shield is entertaining. Even got me a "sorry for glitching you Braum"-comment from opponent's Anivia in post-game lobby xD Quite amusing.

As much as I would love to see a flying man with a shield in future games - the bug is kind of annoying in the middle of a teamfight. Havent found people to join me in re-creating the scenario, though.
