Note that item subclasses should not rely on all other items being present in the layout at the time this method is called. Instead, any connections and links to other items must be made in the finalizeRestoreFromXml() method. E.g. when restoring a scalebar, the connection to the linked map's signals should be implemented in finalizeRestoreFromXml(), not readPropertiesFromElement().
