Howling Abyss Terrain Bug

In the Howling Abyss, there is a spot in the back of the purple side middle bush where you can be boxed in by even a lvl 1 W. I don't think this is very thing, as champions like or even will either die or burn their flash. Yes, I know that with Azir's new ult, there are many ways to box people in SR, but most walls in SR thin enough to jump back, and each wall is situational, as you don't need to constantly fight at the same area.
