Select some text and press Ctrl-K. A link inspector will show, and after a moment, an auto-complete. It's quite likely that an article with this precise title appears in the same wiki, but in the current auto-complete algorithm it won't necessarily appear first in the list, even though it makes sense for it to be first - intuition tells me that that's probably what the editor wants. I cannot reproduce this consistently, but it happens to me currently with the string "Àrea de lliure comerç" in the Catalan Wikipedia.
This is partly a bug in our search backend, but it can also happen because we choose to deprioritize redirects and disambig pages and list them in a separate section.
