[Gameplay] Hunter's Talisman not Interacting with Diana's Passive

Edit: This affects many more champions than Diana. It is a significant nerf to jungle sustain for the following champions:

A listing of all affected abilities I could find was added to the bottom of this post.

Description: Hunter's Talisman does not properly trigger when jungle monsters are damaged by Diana's passive.

Frequency: 100% of the time

Effect on Gameplay: Diana's first clear when jungling is much more difficult and requires her to return to base after fewer camps.

Expected Behavior: After the third area of effect swing, enemies damaged by the passive would have their health drained by the Talisman and would have the purple fire visual effect to indicate this. Because of the description for the Hunter's Talisman stating that any damage on a monster will trigger the health drain effect, it is expected that the damage caused from Diana's passive would cause it to trigger, which leads me to believe this is a bug.

Actual Behavior: After the third area of effect swing, enemies do not receive the purple fire visual effect and their health is not drained.

To Reproduce: Begin attacking a jungle camp with more than one monster as Diana without using any abilities. Monitor the health of one of the secondary monsters after beginning to attack. Health of the monster will reduce when damaged by the area of effect passive but will not continue to tick afterward for the drain.

Edit: Several champions are affected by this bug. See below.

The following champions' abilities are affected by this bug: Passive Bleed Passive AoE attack Passive burn damage Turret basic attacks (lasers properly trigger it) Titan's Wrath damage Passive AoE attack Queen's Wrath AoE damage Jack in the Box Ricochet secondary targets Toxic Shot poison damage Basic attacks from any ghoul
