[Gameplay] Lissandra's E terminates on killing a large minion/monster

Severity: Minor, this is hardly a problem except when trying to wave clear with E.

Reproduction rate: 9/10, occurred on each test aside from one.

Lissandra's E projectile instantly terminates and removes the ability to re-activate E upon killing a large minion or monster, tested on cannon minions, krugs, raptors, red buff. I'm fairly certain this isn't intended behavior as I couldn't find anything about it on the wiki. I haven't tested this on champions, but it's possible that would trigger the same interaction. There doesn't seem to be any problem killing numerous small minions with the skill, nor damaging large ones without killing them.
