Steps to replicate the issue (include links if applicable):
- Make sure that "Do not show page content below diffs" is disabled in your preferences on en.WP.
- Go to a typical Watchlist diff link like https://en.wikipedia.org/w/index.php?title=Wikipedia:Village_pump_(technical)&curid=3252662&diff=1203893569&oldid=1203863882
What happens?:
- Observe that the full rendered page does not display below the diff.
- The text "&title=Wikipedia%253AVillage_pump_(technical)&diffonly=1" is appended after the URL in the browser's address bar
What should have happened instead?:
- The full rendered page should display below the diff.
- The URL should not have the extra text appended.
Software version (skip for WMF-hosted wikis like Wikipedia):
