      Debug Info

      side effect of ZK-3943
      https://github.com/zkoss/zk/blob/6f10f381f2bc470876b96d89ae15619ebb5aec73/zul/src/archive/web/js/zul/wgt/Notification.js#L228
      Typically _fixarrow needs a ref object, but no argument is given.

      Workaround

      zk.afterLoad('zul.wgt', function () {
          var xNotification = {};
          zk.override(zul.wgt.Notification.prototype, xNotification, {
              reposition: function () {
                  this.$supers('reposition', arguments);
                  if (this._ref) this._fixarrow(this._ref);
              }
          });
      });
