New Lioneye's Glare doesn't repeat with Barrage / Barrage of Volley Fire

The "Attacks you use yourself repeat an additional time" does not seem to work with Barrage.

When testing with my other skills, it fires two skills one after the other - however when you use Barrage (especially noticeable with Volley Fire because of the spray at the start and end) it doesn't do that. It fires just the one iteration, and then stops.

Barrage doesn't look like a repeatable attack, but yeah, it's nowhere stated.
