Monali-ITT opened a new issue #10733: Treemap: setOption method refreshes the output while downloading image.
URL: https://github.com/apache/incubator-echarts/issues/10733
 
 
   ### Version
   4.2.1
   
   ### Reproduction link
   [https://jsfiddle.net/xgmr7ovh/3/](https://jsfiddle.net/xgmr7ovh/3/)
   
   ### Steps to reproduce
   1. The output of sunburst displayed correctly on UI which don't have a title.
   2. Click on any one part of a sunburst. The output gets expanded.
   3. Click on the download where we have added a title to the image.
   4. While downloading, it again refreshes the output and displays the original image of the sunburst.
   
   ### What is expected?
   - It should display and download the image with current state and title [without refreshing image state].
   Or
   - We should able to add title at the time of downloading without refresh the image data. 
   
   ### What is actually happening?
   -  While downloading it refreshed the output and changed the state of image and downloads that image.
