Special:UserRights has a table inside a paragraph which is invalid html.
The validator will except the open <p> but than gives a error on the
closing </p>: "No p element in scope but a p end tag seen."
IE11 also gives a hint on the console (hint HTML1509).
Fixed this by just removing the paragraph.
