[Gameplay] Caitlyn auto attacks register immediately upon clicking target

While playing Caitlyn, the auto attack damage registers instantly when acquiring a target. Normally, the auto is fired, the projectile hits the target, the target take the resulting damage. But here, the projectile only begins firing and the damage is already done. This only happens on occasion, though it is still noticeable.

1 - Play Caitlyn ... 2 - Auto attack something ( right click ) 3 - As soon as the click is made the target will immediately receive the damage ( does not happen 100% of the time )

This happened in my last game as Caitlyn. I initially thought that this was a problem on my end, but my duo partner, who was in a call with me, could also notice it.
