      // 1. the element is able to have focus and selection.
      // 2. if element was to flash render it has minimal visual impact.
      // 3. less flakyness with selection and copying which **might** occur if
      //    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.

      // doesn't work as this gives a negative w/h on some browsers.
