Could this possibly give you more than you want? For example, if we made a div
focused and that div parents the rest of the page content.

         parent.loadInlineTextBoxes();
         break;
       }
       ancestor = ancestor.parentObject();
     }
   }
 
   bool is_iframe = false;
   WebNode node = parent.node();
   if (!node.isNull() && node.isElementNode())
