        [codereviewtool] focus first visible node if no node is focused
        https://bugs.webkit.org/show_bug.cgi?id=54935

        Now hitting j/k/n/p will focus the first/last visible node
        if no other node is focused. Also tweaked the scroll into view
        logic a bit to avoid scrolling in this case.
