On https://secure.wikimedia.org/wikipedia/en/wiki/Wikipedia:Sandbox?oldid=453248668, the code
<nowiki>{{fullurl:TEST}}</nowiki>
gets converted to a link
https://secure.wikimedia.org/wikipedia/en/wiki/TEST
but on http://en.wikipedia.org/wiki/Wikipedia:Sandbox?oldid=453248668 it is only a string of text:
//en.wikipedia.org/wiki/TEST

It should be a link in both cases, as it used to be prior to protocol relative URLs.
