        simplify keyboard handling in code review tool
        https://bugs.webkit.org/show_bug.cgi?id=52407

        Now that we have DiffBlock containers, the only things that are
        focusable are previousComment nodes and DiffBlock containers
        that contain add/remove lines.

        Also, this means we show the focus border around the entire diff
        instead of just the first line.
