nput-container listens to those events. Since there are more
      // pending work on focus/blur in IronControlState, I'm putting in this hack to get the
      // input focus state working for now.
      if (!this.$.container) {
        this.$.container = Polymer.dom(this.root).querySelector('paper-input-container');
        if (!this.$.container) {
          return;
        }
      }
      if (focused) {
        this.$.container._onFocus();
      } else {
        this.$.container._onBlur();
      }
    },
