// Textarea and select clone() bug workaround | Spencer Tipping
// Licensed under the terms of the MIT source code license
// Motivation.
// jQuery's clone() method works in most cases, but it fails to copy the value of textareas and select elements. This patch replaces jQuery's clone() method with a wrapper that fills in the
// values after the fact.
// An interesting error case submitted by Piotr Przybyl: If two <select> options had the same value, the clone() method would select the wrong one in the cloned box. The fix, suggested by Piotr
// and implemented here, is to use the selectedIndex property on the <select> box itself rather than relying on jQuery's value-based val().
