### 更新日志

版本 | 说明
--- | ---
8.3.0 | Calling this method on a node without a parent is now a no-op to align the behaviour with the DOM specification. Previously this threw a DOMException with code `DOM_HIERARCHY_REQUEST_ERR`.
8.3.0 | Calling this method on a node without an owner document now works. Previously this threw a DOMException with code `DOM_HIERARCHY_REQUEST_ERR`.
