Icicle Mine of Sabotage Aura does not work on Cursed Enemies

While doing some testing for graft builds I stumbled upon this very weird bug/interaction.

The Icicle Mine of Sabotage aura that grants increased critical strike chance with hits against enemies in range seems to not apply its effect if the enemy is cursed.

Here's a video demonstrating it:

Testing methodology:
1. Use Shade of Solaris wand for the line "Critical Strikes deal no Damage"
Have 100% crit chance with Icicle Mine of Sabotage aura stacked on enemies, resulting in zero damage to said enemies.
2. Have less than 100% crit chance without the aura (~30% in this case), meaning enemies would take damage when it's not active.
3. Verify that enemies take no damage when at 100% crit chance and the aura active.
4. Apply a mark and/or curse to the enemy, verify that the enemy can take damage even though the aura is supposedly active.
