    tree: adjust for Adwaita theme changes
    
    We want the selection bar to line up, not the top coordinates of the
    window. So adjust based on the top padding of the menu.
    
    If someone would like to make this dynamically track padding from the
    menu, a patch to do so would be reviewed.
