[7.9] Quinn Bug in regards to Fiora's Riposte

Today I was playing a game as Fiora against Quinn, and her Q blinds Fiora even if she Ripostes. According to the (unofficial) League of Legends Wiki (http://leagueoflegends.wikia.com/wiki/Sight (under the nearsightedness section)) Quinn's Blinding Assault is considered a debuff. Riposte's skill definition in game is:

> Fiora poises to strike in the target direction, becoming invulnerable to non-turret damage as well as gaining crowd control and **debuff **immunity for the next 0.75 seconds. Fiora is immobile while poised.

I was very scared, for the first time in my life I felt threatened as Fiora :(
