[GAMEPLAY] Poppy Heroic Charge and Bard Mystical Journey

I was fleeing from a Poppy via my Mystical Journey (The long section of the Red Buff walls). I had made it most of the way through [maybe 7 Teemos?]. Poppy must have started Heroic Charge as I was starting the portal. So Heroic Charge pulled me back to slam me into the wall for a stun. It felt weird. It seemed very timing reliant.

From what I remember it occurred similar to:

1. Bard creates a portal and starts going into the journey
2. Poppy casts charge from almost max range (to give Poppy some Travel time to give Bard a chance to go pretty far in the tunnel) as Bard enters
3. Poppy should pull Bard back and run her into the wall.
