RF + Elemental Focus

The mouse overlay for the Elemental Focus gem in-game indicates it will not work for Righteous Fire -- there's a little red "x", just like there is for controlled destruction.
But in Path of Building, it is the best support gem I can get my hands on.
Am I correct in assuming that Path of Building is calculating the damage correctly and that the in-game overlay is somehow bugged or wrong?

The UI element you're talking about takes into consideration the gems already linked to your RF.

If your RF is already being supported by Elemental Focus, linking it to a second Elemental Focus will not confer further benefits--but it doesn't have a separate way to indicate that, so it shows that red X instead.
