Akali Bug That Caused Me To Die Multiple Times

On Akali, when you cast your W, for a good second and a half or so, people can still auto attack you. It's not one of those situations where they already were mid melee animation of hitting you and it just finishes as you cast it, it's more of me casting it, moving a good 200 units away, and then they right click me. Killed me multiple times when Udyr used his E. Check my recent game as Akali. They were multiple situations where I could have outplayed them and won, but instead I ended up dying because they can auto attack me without true sight through my W.
