[GAMEPLAY] Spellthief's Edge doesn't proc every hit on Fiddle's crows

I use Spellthief's edge and take Fiddlesticks' "Dark Wind" at the start of the game. The crows bounce off of enemy champions but only proc the Spellthief at random.

-I could hit champions 4 times and get 1 proc, or I could hit them 2 times and get both with no issue. -The crows could bounce off of an enemy champion and a minion twice and count both times. -I could throw a crow at the first enemy minion, have it bounce all the way off-screen, hit an enemy champion far away and still count as a Spellthief proc. -This can occur on all champs, I haven't seen a game where this does not happen.

You can reproduce this any time by bouncing the birds off of champions and see that the procs can work 100% of the time or sometimes not at all. It is not a question of whether the birds work, they do. It's just not always counting every contact with a champion.
