Re: [pgAdmin4][Patch]: RM #3589 Allow user to save/download Explainplan as JPEG/SVG format

Hi Hackers, 

I am currently working on Feature 3589 "Allow user to save/download Explain plan as JPEG/SVG format."  I have added one download button to the toolbar in "Explain" tab, when clicked it will download the explain plan as a SVG file.

To add this feature I'll have to modify the logic, so instead of providing relative path of each plan (svg image), I have embedded the binary data which is required to download the Explain plan.

I have tested it on following:

• Chrome (Working Fine)
• FireFox (Working Fine)
  
• Microsoft Edge (Working Fine)
• Safari 10.1 and above. 'Download' attribute support is added in 10.1 https://developer.apple.com/library/archive/releasenotes/General/WhatsNewInSafari/Articles/Safari_10_1.html
• Internet Explorer (Images are not rendered, shown X icon.). Please refer attached image.

Attached is the working patch for the above except Internet Explorer. I have tried a lot to figure out the solution, but unable to fix the issue. Need help/suggestions how to fix the issue on Internet Explorer.
