You're right, there is no notification to stack-header widgets of their selection state. I'll make a note to add a standard way for them to be notified of this.
As for standard CSS, with the current design (i.e., your own widget is the only header element), there's nothing to add a default style to. Perhaps we can find a way to add a default "wrapper" element to each stack header, but such that the header widget still fills the space.
