Probably because that is what the HTML specification tells them to
do. :-)
The OP has an XHTML doctype, but is serving the document as text/
html. The document is treated as HTML, any attempt to set a value for
the disabled attribute is ignored as junk. The presence of the
attribute is sufficient to disable the element.
The document isn't valid XHTML anyway:

"Correct" if that is being done in XHMLT markup, but not through DOM.
If setAttribute could be relied upon, and you were in fact dealing
with an XML document, the "correct" way would be:
element.setAttribute('disabled', 'disabled');
However, setAttribute is broken in some browsers and therefore should
be avoided in HTML documents. The simplest, cross-browser way is to
set the DOM property to true or false.
