Why can't I add a wikipedia URL to a release?

@jesus2099, I tried doing like you said but then only the wikidata link appeared in the sidebar, no link to the wikipedia article so I added both, so I guess MB doesn’t add wikipedia link automatically when adding a wikidata url.
Looks like there is a ticket for this as well: http://tickets.musicbrainz.org/browse/MBS-6239

The Wikipedia excerpt (page top) only requires Wikidata link.
But the right‐hand sidebar does not show automatic Wikipedia links, indeed.
In the meantime, I have made a Wikidata→Wikipedia module in the ALL LINKS userscript.
