SUID not working with initial refresh in IE9

[Ciantic]

Hello!

Go to this url with IE9:

http://www.minzi.fi/syksy2011/syksy-2011-12/#/syksy2011/syksy-2011-2/?&_suid=132120559112503867395538328913

It does not work, it gives different than without suid:

http://www.minzi.fi/syksy2011/syksy-2011-12/#/syksy2011/syksy-2011-2/

So SUID is not working?

Update: In Chrome the both links works just fine, so it is bug in HTML4 side of the history.js.

I faced the exact same issue as well in IE9. Any progress/workaround so far?

Is this fixed in current 1.8b1 release?
