[Gameplay] Yasuo Cannot Auto-attack

I encountered this bug today playing a Normal (blind pick) match.

After dashing to an Akali who at the same time used her shroud (and went invisible) I experienced two things. First, Yasuo briefly maintained his "dash" animation, moving around the map while still looking as if he was dashing. Second, and more importantly, I lost the ability to auto attack targets. I exited and reentered the game to no results. This bug persisted until an enemy Rammus taunted me, forcing me to auto-attack. After this, full function was restored.
