Sorry, but this change
http://svn.wikimedia.org/viewvc/mediawiki/trunk/phase3/skins/common/wikibits.js?r1=44192&r2=44774
breaks the interface of function getElementsByClassName. In the original
implementation, oClassNames could be a regular expression such as 'wp\\S*', or
a list of strings! In the native implementation in Firefox 3, the parameter can
only be a single string, see
https://developer.mozilla.org/En/DOM/document.getElementsByClassName
As a result, a call like

getElementsByClassName (elem, '*', 'wp\\S*');

now returns an empty array, whereas it previously returned all child elements
of elem having a class that started with "wp". This change breaks some
functionality in the upload form on the Commons.

Calls like

getElementsByClassName (elem, '*', ['class1', 'class2']);

also won't work anymore.
