Flurry Crazy attack speed bug

So ive been testing around with this build alot with the bug so heres what i think might cause it
First arrow storm passive, it keeps on while channeling
Channel flurry this bug also works on melee version as far as i know
and perhaps arrow storm skill node also

Heres some extra info:
The bug resets if you log out so if i log out i get normal attack speed and the longer im in the game the more attack speed i get and suddenly after playing for about 1 hour 30 minutes you see This crazy attack speed come and go until it stays forever

(another thing to note is that if you respec your flurry skill you will keep the attack speed and when you spec into it again you get even more attacks) Not 100% if thats exactly how it works but theres something there
