Comment:

 I believe this is because most of WP's JS tries to use prototype's
 Element.x functions as extensions to the native JS element object like
 good little object oriented scripts.

 But those extensions aren't reliable in all browsers.  It's better to use
 Element.hide($('element_id'));, for example, than $('element_id').hide();

 Patch

  1. Converts all WP core JS to use Element.method(el) rather than
 el.method();
  1. Fixes wp-ajax JS parser for IE 7.
