19  // *** This styling is an extra step which is likely not required. ***
20  //
21  // Why is it here? To ensure:
22  // 1. the element is able to have focus and selection.
23  // 2. if element was to flash render it has minimal visual impact.
24  // 3. less flakyness with selection and copying which **might** occur if
25  //    the textarea element is not visible.
26  //
27  // The likelihood is the element won't even render, not even a flash,
28  // so some of these are just precautions. However in IE the element
29  // is visible whilst the popup box asking the user for permission for
30  // the web page to copy to the clipboard.
31  //
32

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