$cloned = $(this).clone(true);

$elements = $(this).find("*").andSelf().filter("textarea, select");

$clonedElements = $cloned.find("*").andSelf().filter("textarea, select");

The above snippet gets all elements in the set of $(this). It filters for textareas and selects in the original set and a cloned set. The elements in the sets have different orders, more precisely, they are sorted by type, first textareas then selects. The filtered elements from the cloned set are in a different order. Sometimes this only works once after page reload.

If you filter elements like this:

$clonedElements = $cloned.find("textarea, select").andSelf();

they do not get a new order.
