    alternateTab: Fix Escape not dismissing popup
    
    Since shell commit dd85670f8b25, the handler got a return value to
    determine whether Escape should be handled automatically; we do
    want this for the window switcher, so add an appropriate return
    value to restore the expected behavior.
