Archdemon Crown + Runegraft of Gemcraft + Awakened Elemental Focus (lvl6) synergy

I got my Righteous Fire Skill placed in my Archdemon Crown together with Elemental Focus lvl 6.
EF gets +1 level of supported elemental skill gems at level 5.
since its placed in an archdemon crown it has only level 4. I thought it might be a great idea to use Runegraft of Gemcraft in my Skilltree. It actually displays my Elmental Focus as level 5 (-2level from Item / +1level From Global modifiers) but Righteous Fire doesnt get the extra +1 Level.
