[GAMEPLAY] Dragon buff animation applied to dead enemy in the FoW

While playing a team builder game, I noticed that the dragon buff animation was applied to a dead enemy that was in the Fog of War.

1.) The enemy was killed. 2.) We had no vision of the dragon. 3.) When the dragon died (or supposedly died), I noticed the animation over the corpse of the enemy in the FoW. 4.) The enemy still had not spawned when this happened.

I have not been in the situation to see the bug since. This happened a few days ago on patch 5.8
