[GAMEPLAY] Mordekaiser- Bug which crowd controls Mordekaiser against Fiora's Riposte

I have never reported a bug before but there is one bug that has been bugging me. Thank you Phreak. When you play against Fiora as Mordekaiser the Q mace of spades ends up being considered a crowd control. This bug only happens if you get hit by the actual sword part of Riposte at the end of the blocking. And when it does it stuns you for a second which prevents you from attacking which then prevents you from finishing off the Q (Mace of Spades) chain. This will happen every time Fiora hits her parry. Skins do not matter as I use the base Mordekaiser skin and I have played vs many Fiora skins. Sorry I don't have a link to show it but try it in a custom game.
