1) Open: http://en.wikipedia.beta.wmflabs.org/w/index.php?title=Testing&action=history 2) Click in the second revision of that page: http://en.wikipedia.beta.wmflabs.org/w/index.php?title=Testing&oldid=55042 3) Click on "← Previous revision": http://en.wikipedia.beta.wmflabs.org/w/index.php?title=Testing&direction=prev&oldid=55042 4) MediaWiki will show the second edit instead of the first. This bug doesn't happens on English Wikipedia: 1) Open the history of a page such as https://en.wikipedia.org/w/index.php?title=Wikipedia:Sandbox&dir=prev&offset=20120126182302&limit=3&action=history 2) Click on the link to one of the edits, such as https://en.wikipedia.org/w/index.php?title=Wikipedia:Sandbox&oldid=473372238 3) Click on "← Previous revision" or "Newer revision →" The content of the page will be what the user expects.
