研究方向
Investigate the Tree component's handling of DOM refs, especially offsetHeight. The error occurs when rendering in a new window, suggesting a timing issue or missing DOM element. Check the StackBlitz demo for context and look at antd's Tree source code in the repository, focusing on virtual scroll or measurement logic.
