Flame Breath CD reset

Primal skill Flame Breath is a channeling skill that has CD. When you start using it, CD starts as well. But if you are channeling it for whole CD duration, when you land it starts again.
Here is hope that it is a bug and not intended behaviour, build with CDR and movement speed penalty reduction that can fly forever (as long as you have rage) seems very fun and I would hate to lose it.

Videos down here are meant to last only for couple days as per Steam policy.

How CD behaves when you flying for it's whole duration: https://cdn.steamusercontent.com/ugc/16792537693030643226/0FA78408232AD8443D2F555DC166F524B0BA5C01/

Fun follow-up, Flame Breath skill also does not have Lightning tag, even though it adds lightning damage.

A further follow up on this. When you use Flame Breath and channel it long enough for the initial cooldown to go by and then land, with the skill going on cooldown, you can use the Flame Breath again despite it being on cooldown in Ability bar and your character commenting on how they cannot use it. It'll display the flying animation and deal damage, but the actual Flame Breath will not play.
