Ember fusillade cosmetic not working with unique staff

Currently the demonfire cosmetic does not work with the "on cast" ember fusillade skill from dusk vigil ashen staff.

Ember fusillade only from the skill gem will have the skin, resulting in a visual mix. Blackflame covenant passive node does change the visual for all projectiles, for this reason I believe cosmetics also should.
