Lioneye's Glare Barrage Effect inconsistent

The barrage effect on Lioneye's Glare has been inconsistent for the last month(iirc). Before, upon killing any enemy that is close by, you would get the barrage effect back since there are now no more enemies in your presence. Now, however, you still do not get the effect after killing enemies in range.

My best guess is that corpses are counting as "enemies in range" for the sake of the barrage effect. One, I assume that is not intended design because imo that sounds silly, shouldn't the downside disappear once the player kills the offending enemy? Two, This makes mapping at a high level impossible without dying, due to enemies becoming permanent fixtures that disable the bow's main draw once they die.
