 * @event dsa-expand - Emitted when the tree item expands.
 * @event dsa-after-expand - Emitted after the tree item expands and all animations are complete.
 * @event dsa-collapse - Emitted when the tree item collapses.
 * @event dsa-after-collapse - Emitted after the tree item collapses and all animations are complete.
 * @event dsa-lazy-change - Emitted when the tree item's lazy state changes.
 * @event dsa-lazy-load - Emitted when a lazy item is selected. Use this event to asynchronously load data and append
 *  items to the tree before expanding. After appending new items, remove the `lazy` attribute to remove the loading
 *  state and update the tree.
