我们公司使用了micro-app集成分系统，分系统用到了百度echarts，图标保存为图片，在分系统里使用正常，但是在集成到主系统之后就不好使了，保存不了图片，报错：
Uncaught TypeError: Failed to construct 'MouseEvent': Failed to read the 'view' property from 'UIEventInit': Failed to convert value to 'Window'.
Uncaught TypeError: Failed to construct 'MouseEvent': Failed to read the 'view' property from 'UIEventInit': Failed to convert value to 'Window'.
