Secondary Damage doesn't receive Elemental Damage buff
As the title states, damage inflicted as "Secondary Damage" doesn't receive the elemental damage buff in the proper locations.
For example, Dangerine does x3 damage to Sewer zombies, which is applied during contact hits. However, his secondary damage, being his DoT corrosive effect, does NOT do x3 damage to Sewer zombies.
This makes no sense, as if Sewer zombies are weak to "Corrosive" plants, then wouldn't the actual corrosion do extra damage?
This applies to other plants such as Winter Greens, Gremonade, Lime-Bomb, etc.
On a side note, according to the patch notes: "Ice Plants are significantly stronger in Volcano" for example, but they only seem to be strong against Volcano zombies specifically, not all zombies in Volcano. Wondering if that's intentional or not.
