        linkTrees(xmlDoc.firstElementChild!, root.firstElementChild!);

        const phantomWrapTemplate = "<span class='_phantom_wrap'></span>";
        $($.data(targetDataNode, "wed_mirror_node"))
          .wrap(phantomWrapTemplate)
          .after("<span class='_phantom'>Boo</span>Blip")
          .wrap(phantomWrapTemplate);

        const dataNode = targetDataNode.parentNode as Element;
        // Wrap twice for good measure.
        $($.data(dataNode, "wed_mirror_node"))

        assert.equal(guiPath, dataPath);

        // It should also be reversible.
        assert.equal(rootObj.pathToNode(guiPath), targetGuiNode);
