[Gameplay] Akali killed me while charmed

Ahri & Akali Akali dove in to kill me and we were like right on top of each other. It looked like after i charmed her she was able to kill me. i watched the replay and it looks like she threw out her mark while under charm. based on what i could see we both cast at about the same time except my charm hit her before she threw her mark and while she was charmed she threw it. i'm not sure if its a bug or not because i cant find anything saying whether the charmed champions' ability would finish and still go to its target or not.
