Consistent Animation-loop Trick or Treat glitch

I managed to get a video capture of a glitch I've been seeing with my Necro/Marine MM:

Enemies spawned by Trick or Treat knocking can get stuck in an animation loop where they come out of the door, fade away, and then come out of the door again. My mastermind pets can target and attack them, as shown in the video, but they can't attack me. If I set my pets to aggressive and target through them, I can attack and debuff as well.

 

It seems to be more likely to happen when I drop Tide Pool just right up against the door, but can happen without. It's less likely to affect enemies without feet like ghosts, but seems to affect witches, vampires, and werewolves better than 75% of the time. It affects the EBs as well as the other spawns.
