        fix bugs going back and forth between unified and sidebyside
        https://bugs.webkit.org/show_bug.cgi?id=52470

        Now that we're appending DOM nodes directly, we only want to
        get the first ".text" element in the subtree. In the cases
        where there are multiple, their contents are the same.

        Also, when making side-by-side expansion lines, we need to
        clone the contents so we have a second copy to append to the DOM.
