[GAMEPLAY] Riven vs. Fiddlesticks/ cancels spell, continues animation

fiddlesticks against a riven

Riven can cause my absorb (W) to cancel the spell while absorbing. While keeping fiddlesticks floating, unknowing and immoble.

Step by step: When I use Absorb (W). It will stream as usual to Riven. But a stun that Riven does, causes my spell to no longer heal or damage BUT my body still remains in air, floating and immobile as if it was absorbing.

Since the animation does not end, you end up dying.

Im not 100% sure how to recreate, but ASSUMING its a stun at the same time i cast my absorb, but this is only assumption.
