    // 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.
