[Gameplay] Quinn ult bug (ult being canceled incorrectly)

When quinn runs in to any kind of slowing field during her ult it gets canceled. Ex. akali w, iceborn gauntlet slow field (NOT FROM TAKING DAMAGE), triggering jhin trap (not from the explosion). I believe this is a bug because her ult description says champion damage or immobilization effects. I don't believe that immobilization includes slowing effects and none of the examples I gave deal damage.

This bug happens whenever quinn attempts to move through any of the slowing fields listed above. The iceborn gauntlet slowing field that is left on the ground after the initial damage can also cancel her ult.
