[Gameplay] Fearless Ghost Poro bug

Noticed a bug in a game I was playing earlier with the Ghost Poro rune! It's an interaction with Ivern's Brushmaker ability. If a Ghost Poro is spawned in his bushes and then they expire, the poro will not flee when enemy champions come near unless Ivern places another W on top of it. I was able to recreate it in a custom with friends, and have provided screenshots from the game where I noticed it and the custom.

Screenshots here Steps to recreate:

1. Have Ivern and a champion with the Ghost Poro rune on the same team.
2. Create brush with Ivern's W.
3. Have the champion with Ghost Poro activate the rune by standing in the Brush.
4. Wait for the brush to expire without having the poro disturbed by an enemy.
5. The poro now knows no fear.
