[2021] Elemental Hit cannot apply poison

" BabyCain wrote: When using the Pneumatic Dagger base, which states that All Damage from Hits with this weapon can apply poison, elemental hit still cannot apply poison. This is the case even when flat elemental damage is rolled on the dagger to match the elemental damage type of elemental hit.

Thanks for your report, this is intended as ElementalHit can only deal damage of the chosen element and will not apply Poison because Poison is Chaos Damage.
Another example of this is Brutality Support and how it doesn't allow supported skills to deal Elemental or Chaos damage and stops supported skill from applying Poison.
