Void Illusion not scaling with Increased Attack Area Damage

Void Illusion does not receive increased damage from "Increased Attack Area Damage" passives such as Dizzying Sweep, despite being tagged as an AoE skill.

Given: A Monk character with the Acolyte of Chayula Ascendency and Grasp of the Void ascendency skill allocated
When: I allocate an "Increased Attack Area Damage" passive node such as Dizzying Sweep
Then: I should see Void Illusion's sheet damage increase

Instead, the sheet damage of Void Illusion remains the same.

Bump.
