data: should be followed with a MIME type.

"image/jpg" is not a valid MIME type, so this is not a bug and can be closed.

"image/jpeg" is the appropriate MIME type.

see https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs

either the MIME type is given or it defaults to "text/plain..."

MIME type defined:
https://www.iana.org/assignments/media-types/media-types.xhtml
does not define JPEG but links to
https://tools.ietf.org/html/rfc2046
which uses "image/jpeg"

librsvg and wxSVG are correct, the others (resvg,inkscape,batik,chrome,firefox,QtSVG) might violating the specifications by rendering the image but are more useful
