Gameplay Bug - Vel'Koz and Shrooms

Interesting.

To put it simply, when Vel'Koz casts W over a Teemo Shroom, the second explosion of the W actually ACTIVATES the shroom. So any person near it (on the opposite team of Teemo) will still get affected by poison and slow, and Teemo's Luden's Echo effect still applies etc.

Circumstances: ARAM (I was Vel) and were on opposite teams.

Recreating this situation is pretty easy.

Intentional or not? (Because GOSH it was fun popping shrooms all day)
