Gameplay Bug: Tristana V Blitzcrank

I was playing a game today. I was on the opposing side of the map right next to their base gate. (Red side, Bot lane base gate.) Blitz came out of the gate and I E'd him, Q'd and auto attacked a few times then buster shot him and he legitimately flew from his base gate all the way to the mid lane side bush on Baron side lol. It was hilarious and should either happen all the time or never at all.

Thx
