[GAMEPLAY] Zed, Possible Bug? Immune to CC

I recently played a game as Lux, and the enemy team had a Zed.

Throughout the game the Zed consistently teleported (swapped places with his shadow) while he was snared.

Is this a Zed bug or does CC not stop him from swapping? Is this a bug with Lux's snare?

UPDATE ---

I would also like to know the answer to this. Xuiii could you replicate this on video for us?

I don't have recording software. But after playing more games I noticed that Master Yi can Alpha strike out of Lux's snare as well.

_Lux's snare could be the source of both bugs. _
