Haze spirit damage every 20 doesn't work if you gain 2 charges at once over a 20/40 boundary

[gdstr]

Setup: skill level 2 Haze passive (spirit damage every 20 stacks), get an enemy to 19 stacks, then headshot them to 21.
What happens: They tick up to 21 stacks and take bullet damage
What should happen: They tick up to 21 stacks and take bullet damage and spirit damage.
