Fiora vs Mordekaiser Bug

There is currently a bug that if Mordekaiser hits a Fiora with his Q while she parries, he is then unable to use any abilities or auto attack for several seconds after hitting her as if he were stunned. Mordekaiser has no from of crowd control and should not be affected by her parry, except for blocking the damage of the Q that hit her while parrying. This bug is very easily 100% repeatable.
