   ### Steps to reproduce
   1.`echart.init(dom,null{renderer:'svg'})`
   
   2.通过`toolbox`的`saveAsImage`导出图片
   
   图片无法打开
   
   ### What is expected?

   mac报错：'它可能已损坏，或者可能使用了“预览”无法识别的文件格式。'

   我尝试用getDataURL()和blob导出,拿到的结果是`data:image/svg xml;charset=UTF-8,<svg xmlns="http://www.w3.org/2000/svg"`，我猜测，可能是由于svg相关数据没有并转化成base64引起的
