    flap: avoid hiding flap widget when revealing it
    
    If the flap widget is focused in response to the reveal_flap property
    changing then sometimes it is immediately defocused. This is because
    when the animation starts update_child_visibility() can be called with
    self->reveal_progress == 0 which hides the flap widget. Fix this by
    always showing the flap widget when self->reveal_flap != 0.
