    this.usehref = attributes.usehref || "";
  }
  [$getExtra]() {
    if (!this[$extra]) {
      const parent = this[$getParent]();
      const root = this[$getTemplateRoot]();
      const target = root[$searchNode](this.target, parent);
      const leader = root[$searchNode](this.leader, parent);
      const trailer = root[$searchNode](this.trailer, parent);
      this[$extra] = {
        target: (target && target[0]) || null,
        leader: (leader && leader[0]) || null,
