Screenshots no longer have transparent background

[awesomebender03]

Hi, I really like the screenshot feature to share my maps, but recently I've noticed that the screenshots no longer have a transparent background.

When I take a screenshot, the background on the website flashes to white for a second or two while taking a screenshot and goes back to gray which is what I think is giving the files a white background.

I am not a coder, but I think if you put the screenshot feature back to where it was a few months ago with the transparent background, it would fix the issue.

Thank you for all the great work you do with this project!
