// next to the page title (which we want). However, it also causes the
// Contextual Links module to treat the wrapper for the entire page (i.e.,
// the <body> tag) as the HTML element that these contextual links are
// associated with. This we don't want; for better visual highlighting, we
// prefer a smaller region to be chosen. The region we prefer differs from
// theme to theme and depends on the details of the theme's markup in
// page.tpl.php, so we can only find it using JavaScript. We therefore remove
// the "contextual-region" class from the <body> tag here and add
// JavaScript that will insert it back in the correct place.
