HMRouterMgr.getCurrentLifecycleOwner()?.getLifecycle() 获取值为 undefined

代码如下：

```
export interface webParamType {
  url: string
  title: string
}

@Observed
export class ObservedModel {
  controller: webview.WebviewController = new webview.WebviewController();
}

@HMLifecycle({ lifecycleName: 'H5BackPressedLifecycle' })
export class H5BackPressedLifecycle implements IHMLifecycle {
  model: ObservedModel = new ObservedModel();

onBackPressed(): boolean {
    if (this.model.controller.accessStep(-1)) {
      this.model.controller.backward(); // 返回上一个web页
      // 执行用户自定义返回逻辑
      return true;
    }
    return false
  }
}

@HMRouter({ pageUrl: TNPageConstant.TN_WEBVIEW, lifecycle: 'H5BackPressedLifecycle' })
@Component
export struct TNWebView {
  controller: webview.WebviewController = new webview.WebviewController();
  @State model: ObservedModel | null =
    (HMRouterMgr.getCurrentLifecycleOwner()?.getLifecycle() as H5BackPressedLifecycle).model

aboutToAppear() {
    this.model!.controller = this.controller;
  }

build() {
    // NavDestination() {
    Web({ src: 'www.baidu.com', controller: this.controller })
      .domStorageAccess(true)
  }
}
```

HMRouterMgr.getCurrentLifecycleOwner()?.getLifecycle() 获取的值是undefined。帮忙看下原因呢
