Garuda's Dread Mirror can throw you out of the map

[Aikii]

I experienced today in one of my first games as Garuda, that using Dread Mirror on an enemy completely tossed me out of the map, as recorded in the video below: 

It seems that the reason for this happening might be that the drone in the video was unusually close to the room's ceiling, which combined with how the Dread Mirror puts you on top of an enemy might have been enough to cause me to clip out of the map.
