This address the concern brought up by a volunteer, where discussion pages are "red" but actually link to the root talk page, which may have content, and thus the link shouldn't be red.

The extension does not yet hijack the link at all. Discussion tabs of translation subpages will go to i.e. Talk:Community Wishlist/Wishes/W123/fr when it should be Talk:Community Wishlist/Wishes/W123.

Yes, this does mean we have multi-lingual talk pages (not something that is truly supported), but so be it. That's better than scattering comments across dozens of translation subpages that we then have to monitor.

Acceptance criteria

• On translation subpages of wish and focus areas, make the "Discussion" tab link to the root talk page
• The link should be red if said page doesn't exist, blue otherwise, as one would normally expect.

---

Derived Requirement

Update the handling of the "Discussion" tab for translated subpages of wishes and focus areas so that:

• Instead of linking to the subpage’s talk page (e.g., Talk:Community Wishlist/Wishes/W123/fr), it always links to the root talk page (e.g., Talk:Community Wishlist/Wishes/W123).
• The link color follows standard MediaWiki behavior:
  • Red if the root talk page does not exist.
  • Blue if the root talk page exists.
