Steps to Reproduce:
- Add or remove a page to watchlist by clicking the watchstar with JS turned off.
The link that appears on the confirmation screen points to Watchlist - Modified.
The link should point to the same Watchlist - List as you get when you click the Watchlist link on the User Menu.
See the following screengrab for the current behavior.
The confirmation page is provided by core and links to Special:Watchlist not Special:EditWatchlist. The link in the menu points to the list view Special:EditWatchlist - so this is working properly (there are no magic redirects)
This is a bug though and due to the inconsistency between how desktop and mobile behave (on desktop the "list view" is not a destination as such. Fixing the link on the confirmation page would involve hooks and more complexity and I think our focus should instead be on T229716
