isHomepage always return false IE8 Script Console
After some testing, I've also found it to be true that this method returns false any time it's called from the script console in IE8. I'm not sure why, but attempting to do something like this in the script console while visiting Google's homepage will get you nothing but false:

>>document.body.style.behavior = 'url(#default#homepage)'
"url(#default#homepage)"
----------------------------------------------------------------------
>>document.body.isHomepage('http://www.google.com')
false

If you run that bit of code on window load either in-line in the page or via an included JS file from a domain you control (and obviously changing google.com to that domain), the method returns true as expect.
