Infusion weapon (elemental infusion) + Rain of Arrows

Infusion weapon does not work with rain of arrows.

After getting a frenzy and using rain of arrows it consume, the elemental infusion buff icon pops up on toolbar.

The weapon glows indicating there should be an infusion. In this case frenzy (so lightning)

When using rain of arrows again, it fails to consume the infused element.

Other bow skills work, this one does not. Please fix.

P.S. have not tested power charge and endurance charge.
