"Add direct unwatch/watch links to watchlist entries (JavaScript required for toggle functionality)' is broken only when 'Grouped by page' option is enabled. Otherwise, it works with filters.

Looks like this only breaks in grouped ("enhanced") mode, in non-grouped mode it works fine.

Where is the 'Grouped by page' option?

It's in the RC preferences, and also toggleable under the "Show N changes" dropdown, or with ?enhanced=1.

Got it. Thanks. Having the preference for watchlist page grouping under 'Recent changes' is unintuitive IMO. It should live under 'Watchlist' preferences.

Much of the Preference organization is illogical. We are planning to completely reorganize and consolidate the preferences, as detailed in T172350 and its sub-tasks.

The patch makes the 'x'es appear, but they don't actually work in the new UI (neither in enhanced mode nor in non-enhanced mode). When you click the 'x' in the new UI in non-enhanced mode, it goes to a new page rather than using AJAX, and in enhanced mode it does nothing at all.

Checked in betalabs - the direct links to watch/unwatch are displayed in non-grouped and grouped mode:

The action of clicking on watch/unwatch list is difficult to see now in betalabs since there are problems with maintaining proper user sessions. However, the fix worked properly - displaying a popup informing user that the page was, indeed, deleted from the watchlist and crossing out and greying out unwatched pages.

Currently - there are two issues present (most likely due to the above mentioned issue in betalabs).

• missing 'x'

• redirecting to a different page when the cross icon is clicked

I will be re-checking the issue periodically, waiting when betalabs will be more cooperating.

That's how the result of the action of clicking on 'x' is supposed to look :

Re-checked - it seems to be working (betalabs still has some user session handling issues, so often a user is kicked out after clicking on x due to the user session re-assessment).

• All entries on Watchlist are displayed with x. There are log entries - Move log, Protect log etc - that have x. Clicking on it will remove moved/protected pages from a user's Watchlist.
• Grouped changes to a page have x which will remove the watched page.

• After removing a page from Watchlist via x, the page can be added to Watchlist by clicking on +

There is a bug T176684: Unwatch/watch links are not displayed for grouped Move log entries which needs to be triaged.
