Lulu - Whimsy

Lulu - Whimsy = "If cast on an ally, grants them Movement Speed for a short time. If cast on an enemy, turns them into an adorable critter that can't attack or cast spells."

I use google translation:

On Lulu I think it must cancel compétence when poppy press R or Jax E or When Yi R i cant Whimsy him ! you can change that?
