Lucian's The Culling cancels from CC with Edge of Night

Lucian's ulti, The Culling, with the Edge of Night active gets canceled when hard CC gets shielded from said active. I.E.: Lucian activates Edge of Night, starts ulti, Skarner uses hit ulti, which will do nothing since the CC got shielded, but Lucian's ulti will stop.

I've been able to recreate it with every hard CC in the match I first found it in.
