Comment:

 Thank you! This filter `upload_mimes` is the missing piece to reproduce,
 and I was able to do that after adding that filter.
 {{{
 function wp_mime_types($mimes) {
         $mimes['svg'] = 'image/svg+xml';
         return $mimes;
 }
 add_filter('upload_mimes', 'wp_mime_types');
 }}}

 **6.8.1**:
