Thread:Extension talk:Semantic Extra Special Properties/Factbox shows empty

Is there a way to suppress a Factbox if it only contains Extra Special Properties?

I enabled this extension and am using it to capture _CUSER. I wanted to enable Factboxes on all my pages that store an SMW property: $smwgShowFactbox = SMW_FACTBOX_NONEMPTY;

When using ExtraSpecialProperties, all my pages now store a property. Even so, the factbox rendered in the footer of the pages isn't including the _CUSER property.

If I click on the magnifying glass link to go to the Special:Browse page, I can see the properties.
