Technically, it's not a valid SVG. It lacks an opening <?xml...> header, that also indicates which SVG version is meant (because the SVG format is in XML, so the whole SVG file should be conformant XML).
This said, as far as I can tell, 2.10.12 opens all the files at 500x500 by default and this could be a bug. The size is detected correctly on 2.8, but the SVG is not rendered correctly.
You can load the file in 2.10 by forcing the right size: round off the numbers for width and height that you find in the first line
ie, 3279x800. You will have to unlink the X & Y ratios.
Indeed a bug, should be fixed in 2.10.14: https://gitlab.gnome.org/GNOME/gimp/issues/2561
