why is this a todo?

to get the current TabContents, you can do

WebContents* tab = tab_util::GetWebContentsByID(renderer_id, render_view_id)

then Browser::GetBrowserForController(tab, NULL)

+  user_response = browser::ShowYesNoBox(
+        BrowserList::GetLastActive()->window()->GetNativeHandle(), title,
+        message);
+#endif
