[Gameplay] Fizz- Death During Playful/Trickster

When Fizz uses his E (Playful/Trickster) at low health, certain intervals of a point in click ability, such as Wukong's E (Nimbus Strike) can cause him to take the damage anyway while he should be untargetable. The animation for Playful/Trickster plays and he goes up on his pole with the color shift, but he still takes the damage if it were to kill him.

1. Be a low hp Fizz
2. Use Playful/Trickster (E)
3. Within a fraction of a second have a 'point and click' ability hit him -Not sure which abilities also trigger this, I experienced it with Wukong's Nimbus Strike (E)
4. There is no next step, Fizz is dead.

I'm not one that picks fizz that often but this bug has occurred at least 3 times to me in the past 4 months or so, and I have seen this in many other people's games as well. Unfortunately I don't have the means to record it, but i can provide a match history page. Doubt how much that would help.
