  60.   // 1. the element is able to have focus and selection.
  61.   // 2. if element was to flash render it has minimal visual impact.
  62.   // 3. less flakyness with selection and copying which **might** occur if
  63.   //    the textarea element is not visible.
  64.   //
  65.   // The likelihood is the element won't even render, not even a flash,
  66.   // so some of these are just precautions. However in IE the element
  67.   // is visible whilst the popup box asking the user for permission for
  68.   // the web page to copy to the clipboard.
  69.   //
  70.

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

  79.   textArea.style.height = '2em';
  80.  
  81.   // We don't need padding, reducing the size if it does flash render.
