Model attribute value is not rendered correctly when an object

Consider increasing value from 1 to 2 here:

Just keep in mind that:

• IIRC this will also affect the selection/node (object) inspector on the right,
• some attributes have huge nested structures, and printing two levels meant printing really insane stuff, especially, if there was a reference to model/editor/document (any large structure, really). Mentions suffered from this, and although it was fixed at some point it's hard to predict what's in there.
