$.contains fatal error in IE9 when 2nd parameter is null

Description
Summary
Calls to $.contains fail when parameter is null, breaks all scripts.
Reason
The reason for failure is that when element.''compareDocumentPosition'' is called with null in IE9 it returns invalid argument. Returns false in Chrome as expected.
jQuery Version: 1.8.0
Browser: IE9 RTM

Either way, the expected behavior should be the same across browsers.
