Fizz-Annie Stun bug

While in game earlier, I found that troll-poling, or Playful-Trickster, to dodge Annie's AoE w ability doesn't work. If she casted her w while i was on the pole she wouldn't do damage (I don't really remember), but she would still stun me. Therefore I couldn't cast e again to jump further and I would be stunned when coming off of the pole. I don't have a video or anything, but I'm sure I could replicate this with some friends if needed.
