Do we need to store this and |window| separately?  While it's not likely, I'm
worried that they might get out of sync.  Maybe just store |window| and look up
WindowState when needed?

I'll remove window in separate CL as CL is already too big. See
my comment for the reason why I prefer window_state. Added todo.
