[Gameplay] Fiora Riposte not activating stun when hit by Lulu Polymorph

Re-created 100% of the time throughout a match. Fiora's Riposte does not act as though Polymorph is hard CC, and will therefore not stun on a successful parry.

As a side-note, it seems Riposte is acting a bit weird lately? I've seen Yasuo tornadoes not activate the stun and even some displacement effects (Ali headbutt) not proc the stun on reaction. At first I thought I was reacting too late, but that doesn't make sense because the damage component of these spells was negated, while the CC wasn't acknowledged or reflected. Can a Rioter look into this? It's making certain matchups really inconsistent with how the skill is supposed to work.

Another bug (or just weird behavior); Shen cannot dodge Fiora's Q using his shield, while Jax can with his E. Shouldn't both of these skills have the same interaction with Lunge being that they use the same mechanic (dodge)?
