- Create a new page with wikitext "[[中文]]" on zhwiki
- VisualEditor-edit this page and type "s" at the end
- The whole document now looks as if it has a link to "中文" with text "中文s"
- Save the page
- Resulting wikitext is "[[中文]]s", and in rendered HTML (both PHP and Parsoid - bug 41151), "s" is not a part of the link text
