// | |
// Why is it here? To ensure: | |
// 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. | |
// | |
// Place in top-left corner of screen regardless of scroll position. | |

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