Steps to reproduce:
- Enable VE and NWE (with dual tabs).
- Go to https://de.wikipedia.org/wiki/Spezial:Linkliste/Benutzer:Schnark or https://de.wikipedia.beta.wmflabs.org/wiki/Spezial:Linkliste/Benutzer:Schnark
- Try to edit the page.
Expected: Tabs for VE and NWE are present and work.
Actual: In both cases the VE tab is missing. The NWE tab takes you either to OWE (in Wikipedia), or to a page with a note the editor is loading, though it actually isn't, and a link that takes you to OWE (Beta).
