function theme_menu_fields_menu_tree(array $variables) {

  // We check here, if this is the rendering of a single link element as part
  // of a menu fields entity. In that case, the markup has no <li> element and
  // doesn't need the wrapping <ul> neither.
  // The criteria is that their is only a single item in the menu, the menu
  // itself is menu_fields enabled and it's not the rendering of the entity
  // itself (render_menu_fields == FALSE) which could be the case for single
  // link menus.
