Zhonya's denies invincibility after the nexus is destroyed.

I've noticed that from time to time when i played against bots, they actually didn't stop moving and went for me and killed me, even though the nexus was already destroyed. I tested it and found out that it's because i was using Zhonya's before the nexus was destroyed, and the stasis was over after it was destroyed. The stasis apparently makes the user "dodge" the game over invincibility which can end up with an unfair death in some extreme cases like zhonya'ing next to Mundo that W's. Yes, the death is counted into the score after the game, and that can for example end up with missing an S rank. Correct me if i'm wrong, but i'm preety sure that stasis is supposed to make you dodge Kayle's or Taric's ult, but not that.
