    ui-utilities: Pop up context menu near selection
    
    Context menus pop up where the pointer is, which is at the
    selection if the pointing device is used to open the menu.
    
    However, if the <Menu> key or <Shift>+<F10> keyboard shortcut
    are used, context menus still shows up wherever the pointer is,
    which may not be near the selected item at all.
    
    Instead, show context menu near the 1st selected item (or at
    the edges if out of view) when the popup menu is activated from
    the keyboard.
