Similar: when navigating to Internet archive by prepending web.archive.org/web/ to the current url, Orion performs a search instead of navigating to the site.
adding https:// to the front browses to the site, but I only use this occasionally and forget to include the protocol.
web.archive.org/web/https://www.anysite.net is a valid url AFAIK and should be handled the same way as if I typed in www.anysite.net, which does not require the protocol to work as intended.
