1. Go to some unconnected item on a wiki 2. Use the dialog to link it to enwiki / Wikipedia:Sandbox/wikidata-link-redir-bug 3. It says: An unexpected error occurred. 站点链接Wikipedia:Sandbox/wikidata-link-redir-bug-target已被项Q13863609使用。 4. Expected: the page gets linked at Q13863609.
https://gerrit.wikimedia.org/r/71545 should have fixed this. Please reopen if it didn't.
