To reproduce this odd behavior:
- Translate [[Affaire Elf]] from French to English.
- Click on the first paragraph.
- Select "longue" in the first paragraph.
- Click "Link to another page".
- Type "Hello" in the input box and press Enter.
Expected: the word "longue" is supposed to be linked to "Hello".
Observed: the word "longue" is linked to "Kon'nichiwa Anne: Before Green Gables", which is the last item in the dropdown of autocompletions of the world "Hello".
