[GAMEPLAY] Alistar combo Q+W activates E even isn't pressed
~~ Hello,~~
I have this bug when patch 8.5 hit up on

When I cast head-butt combo [Q+W] pressing after E. First time everything is looks fine but.
After second time casting [Q+W] hitting target or enemy champion it automatically triggers E spell even it is not casted.
It is really annoying bug because it makes game play on
nearly impossible, you are going to be pretty mana starved really fast.Please can you guys look after it, I tried on different skins effecting on it bug still happens.
I tried on another PC too, is it only me or some one else having this bug also?
PS. Guys if you read this post please help testing the bug and post some comments and up votes, that Riot will notice this post!
Here is some GIF and picture form keys what I pressed during recording, hope it helps describe the bug.
