    completion sizing: some tests
    
    The scrolled window height can not be smaller than 55 pixels, so when
    the tree view contains one or two rows, the scrolled window is too big.
    
    Another bug: when the scrolled window is resized at a row boundary, we
    can see a little the next row. Probably due to the vertical-separator
    height (one too much).
