modal window not modal in chrome

Question

I'm opening a modal window with javascript like this:

window.showModalDialog('<%=Url.Action("Index","Bank") %>', "Ratting",
            'width=550,height=170,left=150,top=200,toolbar=1,status=1,')

and it works properly in all browsers except for chrome (it's not modal)
I want to know whether is this a bug or a feature? or maybe I'm doing something wrong
