Ekko bug with Static Shiv?

So i was playing ekko in my last game as the jungle and i was pretty fed so i bought a shiv (we won don't report me :p) Well i was farming when i noticed that when I would E to a minion when it was really low so it was one hit froma caster or melee minion to kill it and when it died my E wouldn't go through which is normal but the Shiv would proc even though my E didnt dash or complete to the minion so basically the Shiv would proc before my E actually went through. Not that big of a Bug but still is one :p
