According to https://gitlab.gnome.org/GNOME/glib/-/issues/2511 , this can happen when applications, primarily browsers, call the glib function `g_desktop_app_info_set_as_default_for_extension()`; it creates a new fake "user extension" mimetype, application/x-extension-foo. The unexpected mimetype causes various bugs with applications. That bug report has a workaround to get rid of these mimetypes.
