    window: Handle changes of the attach-modal-dialogs preference
    
    Currently we decide whether a modal dialog should be attached or not
    when mapping it, i.e. we don't pick up preference changes that happen
    while the dialog is up. It's not really a big deal given that modal
    dialogs are usually transitory, but it's easy enough to add a bit of
    extra polish ...
