Steps to reproduce
- Make sure you are logged out of Wikidata (you can use a private/incognito window, or you can use a Firefox container if you use Firefox).
- Go to https://www.wikidata.org/wiki/Special:SetSiteLink/Q42/be_x_oldwiki.
- Look at the paragraph directly above the form.
Actual result
It says Warning: You are not logged in. Your IP address will be publicly visible if you make any edits. If you x oldwiki log in or x oldwiki create an account, your edits will be attributed to a username, among other benefits. Notice how the part of the site ID following the first underscore ended up in the link text instead of the link target.
Expected result
It should say Warning: You are not logged in. Your IP address will be publicly visible if you make any edits. If you log in or create an account, your edits will be attributed to a username, among other benefits.
