• I'd hide all the map controls

There is a mechanism to filter out elements but I didn't try it yet!

The two errors are different, we might hit some limitations at some point, the dom-to-image tool is actually re-rendering the whole page to be able to convert it.

Also https://github.com/1904labs/dom-to-image-more has probably more bugs fixed but we have to retrieve the fix for iframes (see comments at the top of the copied file).

If you wish to load images that reside outside of your pages origin, you can use a proxy to load the images. — https://html2canvas.hertzen.com/faq

So we do not have background tiles in the preview of the map.
