Bizarre Collision in Viscous' Ult

[#1 Cool Veno Appreciator]

Touching an enemy Haze that was in her dying animation caused me to bounce off of her, instead of rolling through as expected. No obvious terrain collision or other interruption. Previously I saw this behavior when Haze was using Unstoppable, and assumed it was tied to that, but this Haze did not have Unstoppable.
