Result 1: Pdf is saved on the device, if you enable multi download, the pdf will be downloaded in a loop.
Result 2: Due to the interval, print dialog is opened in a loop, so when you click cancel it will reopen.
Result 3: Alert will show in a loop,


constructor(document, calculationOrder, objects) {
    this._document = document;
    this._calculationOrder = calculationOrder;
    this._objects = objects;
    this._document.obj._eventDispatcher = this;
    this._isCalculating = false;
  }
  mergeChange(event) {
    let value = event.value;
    if (Array.isArray(value)) {
      return value;
    }
    if (typeof value !== "string") {
      value = value.toString();
    }
    const prefix =
      event.selStart >= 0 ? value.substring(0, event.selStart) : "";
    const postfix =
      event.selEnd >= 0 && event.selEnd <= value.length
        ? value.substring(event.selEnd)
        : "";
    return `${prefix}${event.change}${postfix}`;
  }
  dispatch(baseEvent) {
