Ignite from HoA doesnt trigger Gas Arrow

Why not?
I'm also using armour explosion and it doesnt trigger gas arrow either, but that was expected since it's not a detonation skill even if it does trigger an explosion and ignite enemies (so why not for the ignite part)

Herald of Ash explode and ignite enemies, i assume the explosion doesnt trigger GA because it's a spirit gem, but ignited enemies should, am i missing some wording?

Herald of Ash applies a DoT that the game currently doesn't have coded as a true Ignite. Idk if this is intentional design.
