Auto Attack Sound Goes Off, But No Damage is Done [Gameplay]

This is something that I believe is an unintended bug with Malphite, but it could happen with any other champions that slow attack speeds. When I play vs Malphite as lets say Riven, I run into the same problem every game. When I engage on Malphite and his E slows my attack speed, I end up cancelling all of my autos. This is because during my auto attack animation, it will make the sound that I hit him, but the damage won't go off until about a second later. So every time I hear the sound, I use my Q (part of Riven's mechanics) but I end up cancelling my auto attack. If you don't know, Riven makes a very distinct sound when her AA hits her target, and out of instinct, when I hear that sound I think "Oh my auto attack has gone off, I will use my Q now." But the damage won't go off until a second later and I cancel my AA. It's very confusing to me because the animation for my auto attack gets slowed, but not the sound. Has anyone else run into this problem with Riven Vs Malphite or other similar situations? I don't know if this is an intended thing by Riot Games, or it is a bug that nobody has mentioned because it doesn't affect them as much. I believe that if you guys are going to slow the auto attack animation with slowed attack speed, you would make the sound for the auto attack match the slowed animation?
