While we can upload SVGs, there's been debate as to how thumbs should be stored (same vector asset or bitmap version).
For conversation regarding options refer to GitHub:
Any progress on this? Looks like 1166 is closed without resolving the thumbnail issue (should be separate issue?). Another option for this may be pushing the SVG to a canvas. https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Drawing_DOM_objects_into_a_canvas
Using the full asset presents an issue when width and/or height aren't set in the SVG file, which Adobe Illustrator leaves out when exporting for some strange reason.
