I regularly need to drop an SVG, created with Illustrator, into XD, but it loses the invisible bounding box.
The same thing for export – there just one way to make an asset with a bounding box, and that’s make an invisible rectangle in the icon, but that results in messy code that needs to be cleaned up later for our developers.

It’s basically this request: https://adobexd.uservoice.com/forums/353010-adobe-xd-bugs/suggestions/20219551-while-importing-svg-s-it-does-not-include-boundin
