Champ hitting Yorick Wall

I was playing Akali against Yorick and I noticed that when I was in my shroud and clicked outside the wall from within, I would be forced to hit the wall. This revealed me from within the shroud and made it almost impossible for me to not hit Yorick or the wall unless I used the "Only target champions button". I do not know if this a bug or not, but I would like this to be looked over as it is quite bothersome trying not to hit anything and I believe this might affect other stealth champs as well.
