How is Path of Building expected to behave?

When equipping a forbidden shako with Impending Doom as one of the supports, and adding a curse gem which is socketed into the helmet, then the calculations for Doom Blast from the Impending Doom should show up as an option on the sidebar.

How does Path of Building behave?

When doing the setup above, Doom Blast is not shown and the DPS numbers cannot be seen.

How to reproduce the issue

1. Make new character.
2. Equip Forbidden Shako with Impending Doom and Swift Affliction (anything that wouldn't cause issues for the second support).
3. Add Despair curse as a skill and socket it into the helmet.
4. No Doom Blast shows.

Screenshots

Can see the second bar is greyed out so you cannot select Doom Blast there as you should.

If I add an Impending Doom Support to the link then you can see what it should be showing.
