+  //    the textarea element is not visible.
+  //
+  // The likelihood is the element won't even render, not even a flash,
+  // so some of these are just precautions. However in IE the element
+  // is visible whilst the popup box asking the user for permission for
+  // the web page to copy to the clipboard.
