Certain links (including links inside navboxes) render
links to themselves - for example the navbox on the San
Francisco article (provided it is not removed by
wgMFRemovableClasses)
These links should not look like links as they are not
clickable so should be visually distinguished.
Support for attribute selectors goes way back to IE7
and in the case of IE6, links will still render correctly
falling back to the browser default stylesheet
