Skarner's Ult & Explosive Seed Interaction

So I just had a game where a Skarner was coming at me, I popped the Explosive Seed and made it to the other side of the wall (from river side to blue golem), and Skarner's ult pulls me back over the wall (ignoring collision completely) and back to him. I know this was fixed with Skarner's ult and Flash pulling targets back to him from unreasonable distances, especially over walls.
