Pantheon Stun doesnt work on Gromp

Picture this: you are a veteran Panth JG Player. You've probably done it a thousand times, Blue leash, and straight to gromp, lvling up your W on the way. you wait for your Passive shield to cycle, and when it gets to the right time, you W (jump stun) Gromp. Gromp gives no fucks, and continues to attack you. you die, because you are shaken up and you arent really that good of a player.

More seriously, the purple "Stun" thingey shows up, but Gromp continues to attack through it. Ive noticed it a few times. I havent noticed weather Gromp moves during this time.

In S7 Gromp was stunned and dint attack for the duration. Has this changed? Or is FAKER CONTROLLING GROMP, JUST TRYING TO SCREW ME OVER!" Who knew?

Id love to see this reported and changed. Cheers!
