// 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.

// Place in top-left corner of screen regardless of scroll position.
