    popover: Don't inherit style from parent
    
    Instead, inherit style from toplevel (because that's the default way,
    not because it makes lots of sense).
    
    This way, popovers don't inherit the styling from the widget that popped
    them up, which is a problem in selected listbox rows, selection-mode
    headerbars.
    It also doesn't inherit styling where we might want it, like the osd.
    
    But we can only have one of the two things.
