Can't save canvas as image on Edge browser

I am using fabric js for my web application. For saving HTML5 canvas as image using fabric js, I found the following code which works in chrome and firefox browser. But when i run th same code in microsoft edge, the browser just opens a blank new window without any image on it.

 $(".save").click(function () {
    canvas.deactivateAll().renderAll();
    window.open(canvas.toDataURL('png'));
});

However I also tested many fiddle projects which shows how to convert canvas to an image. Those fiddles works on chrome but not in edge. An example fiddle is here
