if you're up for a little bit of cleanup along the way, pull this stuff into a
helper module and call it from page_action_custom_bindings and
browser_action_custom_bindings (and here).

A good time for this might be in your follow-up.

OK.

   var apiFunctions = bindingsAPI.apiFunctions;
 
   apiFunctions.setHandleRequest('setIcon', function(details, callback) {
     setIcon(details, callback, this.name, this.definition.parameters,

+            'system indicator');
   });
 });
