What do you think of mirroring how setFocusToItem is implemented with something like:

  for (let i = 0; i < this.treeitems.length; i++) {
    const ti = this.treeitems[i];
    if (ti === treeitem) {
      ti.domNode.setAttribute('aria-selected', 'true');
    } else {
      ti.domNode.removeAttribute('aria-selected');
    }
  }

this.selectedItem.domNode.setAttribute('aria-selected', 'false');
}
treeitem.domNode.setAttribute('aria-selected', 'true');
this.selectedItem = treeitem;
};

Tree.prototype.setFocusToItem = function (treeitem) {
for (var i = 0; i < this.treeitems.length; i++) {
var ti = this.treeitems[i];
