[GAMEPLAY] Riot Girl Tristana Ingame Visual Bug

Today I got Trist in the new ARAM map, and picked Riot Girl Tristana. As I was playing, I noticed she was behaving in a strange way with her gun.

This strange interaction occurs when she stops walking, and the gun takes a very strange position, as if she was holding it infront of her, but it doesn't look natural, and I'm pretty sure it's a bug. I don't think that's intentnional, but it's better illustrated on the video that I captured.

The bug happened also in Summoner's Rift, The Crystal Scar and the Twisted Treeline, as I tried Trist in those maps soon after to make sure it wasn't just a thing of the new ARAM map. Upon further testing, I tried out a couple more skins, and the bug seems to be only for the Riot Girl Tristana skin.
