[GAMEPLAY] Tahm Kench's Target Invincible After Devour's Skillshot

On Tahm Kench, when rapidly devouring and then spitting our a unit, they become unkillable for a period of several seconds. Their HP would remain extremely low (like one hit from dying) but would not drop to zero for some reason. This has happened at least twice in my last ranked game playing him. Both times I did take note that I pressing W in rapid sequence for a quick devour and release. Once was on a Scuttle Crab that had 1 HP that refused to die for several seconds. The other time was on an enemy minion that should've died as soon as it was spat back out, but instead lingered invincibly for several seconds as well. During those briefs moments, neither I nor my teammates were able to kill them. I don't have a video, but this did happen twice in the same game.
