I'm the virtual bz ;-)
This works as per the DOM spec. .style should only return the inline styles of
the element. If you want to get the complete computed style of the element you
should use the DOM Level 2 getComputedStyle method. Please see 
http://mozilla.org/docs/dom/domref/examples7.html#998756
for more information.
Marking INVALID.
