Bug 431173 - On Drag start Bookmark item in right pane of Library window, list...

    if (aSelectedNode && !PlacesUtils.nodeIsSeparator(aSelectedNode)) {

      detailsDeck.selectedIndex = 1;

      infoBox.hidden = false;

      // Using the concrete itemId is arguably wrong. The bookmarks API

      // does allow setting properties for folder shortcuts as well, but since

      // the UI does not distinct between the couple, we better just show

    }

    else {

      detailsDeck.selectedIndex = 0;

      // The details deck has the height of its biggest child, so we hide the

      // infoBox to allow it shrinking when there is no selection.

      infoBox.hidden = true;

      var selectItemDesc = document.getElementById("selectItemDescription");

      var itemsCountLabel = document.getElementById("itemsCountText");

      var rowCount = this._content.treeBoxObject.view.rowCount;
