    Web: Update our command state when a braille input event occurs
    
    When the caret moves or focus changes as a direct consequence of an
    Orca command, we don't want to double-present the change. As a result,
    we keep track of the nature of the last input event. Because we were
    not doing this for braille input events, we sometimes had stale info
    and ignored events which should have been processed and possibly
    presented.
