    gtk/treeview: Position editable widgets correctly wrt left border
    
    The coordinates are already widget-local here, not transformed by the
    adjustment positions. Using the adjustment value here ends up pushing
    the entry far from the left border.
    
    The correct minimum value here is 0, which matches the treeview left
    border.
