Fiora riposte is bugged

Fiora's reposte makes her unable to be auto attacked during or after her riposte for quite some time. This occured during games with darius vs her and jax. I could walk up and right click her without pushing anything else and darius would just stand still looking at her, then after 2 or so seconds he would then start up an auto animation. This can be potentially game breaking with higher cdr levels. I know she is immune during her riposte, i know she can stun if hit with hard cc, but when she just mashes the button for no reason i should not be unable to fight her for 3 seconds .75 during and 2 after(glitch).
