    notebook: Fix invalid call to gtk_style_context_get()
    
    Company:  gtk_style_context_get() (and _get_padding/border/color())
    should only ever be called with the same state as
    gtk_style_context_get_state()
    Company:  usually that's a simple replacing of the old state (like in
    the trace you posted)
    Company:  sometimes it requires calling gtk_style_context_set_sate()
    with the right state first
    Company:  and in very rare cases it needs a gtk_style_context_save()
    before the set_state(), too
