[Gameplay] Ezreal E bug

It may or may not be a bug, it may be intended but I've never heard about it before but I just "blinked" a damage spell. I had about 10% health and had a Zilean bomb attached to me, and as it exploded I hit E and the damage did not apply. I'd assume that this could apply to other "attachment" style spells as well but I don't know and don't have the reaction time to properly test it.
