exceljs: Angular Material crashes

Hello all,

I’m trying to use this lib with Angular 8 and Angular Materia, and below is my method

async exportExcel(jsonData: any[], headers: TableColumn[], fileName: string, config?: ExcelRowConfiguration  ) {
    // create workbook and worksheet
    let workbook = new Workbook();
    let worksheet = workbook.addWorksheet(fileName);

    if (!config) {
      config = new ExcelRowConfiguration();
    }

    //config.fonts = excel title config
    //config.alignment = excel header config
    this.generateFileTitle(fileName, worksheet, config);
    this.generateHeaderRow(headers, worksheet, config);
    this.generateDataRows(jsonData, worksheet, headers);
    await this.generateExcelFile(workbook, fileName);
  }

For some reason when the code is like above, my material components acquire stranger behaviors. For example: I click to open a mat-expansion-panel and it expands only if I click in other area, I have to click twice to export table, and other stranger behaviors. But when I comment the method’s body everything work fine. Is known any issue with Angular Material Components and ExcelJS?
