Donwload chart image issue on latest version of Chrome version.61

Download chart as Image is not working with latest version of Chrome.

I think below code is not working any more with latest version of Chrome.

Flotr.addPlugin('download', {

  saveImage: function (type, width, height, replaceCanvas) {
    var
      grid = this.options.grid,
      image;

    if (Flotr.isIE && Flotr.isIE < 9) {
      image = '<html><body>'+this.canvas.firstChild.innerHTML+'</body></html>';
      return window.open().document.write(image);
    }

    if (type !== 'jpeg' && type !== 'png') return;

    image = getImage(
      type, this.canvas, this.ctx,
      this.canvasWidth, this.canvasHeight,
      grid && grid.backgroundColor || '#ffffff'
    );

    if (_.isElement(image) && replaceCanvas) {
      this.download.restoreCanvas();
      D.hide(this.canvas);
      D.hide(this.overlay);
      D.setStyles({position: 'absolute'});
      D.insert(this.el, image);
      this.saveImageElement = image;
    } else {
      var u = navigator.userAgent, isIE = (Flotr.isIE || (new RegExp(/(trident).+rv[:\s]([\w\.]+).+like\sgecko/i)).test(u) || (new RegExp(/(edge)\/((\d+)?[\w\.]+)/i)).test(u));

      if (isIE) {
          return window.open('about:blank').document.body.innerHTML = '<img src="' + image.src+ '">';
      }

      return window.open(image.src);
    }
  },

window.open(image.src) open a new tab window but it is blank and do not display chart image.
