Salvo support gem only ever firing 1 projectile [VIDEO]

Using Salvo with Lightning Spear DOES fire projectiles in random directions, but never more than one at a time, even when 3 seals have accumulated.

Video shows:
1) Normal behavior
2) Salvo behavior
3) Salvo with all seals accumulated (only 1 projectile)

Never mind - I see the Lightning Spear tooltip dictates “modifiers to the number of projectiles fired only affect the maximum number of lightning bolt projectiles”.

Still… it’d be nice if the random flight patterns were also applied to the lightning bolts rather than the spear.
