Ekko E bug (when used on LB)

So basically this LeBlanc was chasing me like crazy and I was gonna outplay her (yo yo yo) and E to her. She basically used her W then her ult towards me, I used my E and as soon as I pressed on LB, she also pressed on her W to go back to where she started from after realising she's gonna get rekt. Problem is, I did click on her and she did teleport back... But so did I. I was literally transported half a map back, right to her but did not get the kill, why? Because I didn't realise I teleported back. My screen simply went black (fog of war) once I E'd on her and I was like wtf what happened where is my champ?? Once I looked on the minimap I realised I was waaaaay back, right next to the enemy teams turret (hella dangerous) but luckily their LB kept running away as she was screaming "WTF?!?!?!" in all chat. So was I, obviously - who had to get the shit out of that turrets sight lol.

TL;DR: I e'd to a LB who used her w, teleported back to where LB went but my screen did NOT relocate and stayed in the same spot where I initially was (before using my e. Also my screen is always unlocked).

No idea if this is working as intended or not (being able to E back to leblanc, though it seems legit due to the fact that Ekko's E is literally a teleport) But I do hope you fix the relocation of the screen according to where Ekko E's.
