HarmonyOS鸿蒙Next中使用Preview预览器发现Navigation子页面无法正常显示

HarmonyOS鸿蒙Next中使用Preview预览器发现Navigation子页面无法正常显示 使用Navigation跳转到子页面，Preview预览器无法正常显示子页面。请问是bug 吗，模拟器上正常显示,

代码如下：

import { hilog } from "@kit.PerformanceAnalysisKit";

export interface INavigationDestinationParam {
  id: string;
}

@Entry
@ComponentV2
struct Home {
  @Local
  private pages: NavPathStack = new NavPathStack();

  build() {
    Column() {
      Navigation(this.pages) {
        Index({ pages: this.pages})
      }
      .title('标题')
      .titleMode(NavigationTitleMode.Mini)
      .mode(NavigationMode.Stack)
      .hideBackButton(true)
    }
    .height('100%')
    .width('100%')
    .backgroundColor($r('sys.color.point_color_checked'))
    .expandSafeArea([SafeAreaType.SYSTEM], [SafeAreaEdge.TOP, SafeAreaEdge.BOTTOM])
  }
}

@ComponentV2
struct Index {
  @Param @Require
  pages: NavPathStack;

  build() {
    Column() {
      Button('测试')
        .onClick(() => {
          this.pages.pushPathByName('detail', { id: '123' } as INavigationDestinationParam);
        })
    }
  }
}

@Builder
export function buildDetail(param: Object) {
  Detail({ detailId: (param as INavigationDestinationParam).id })
}
@Preview
@ComponentV2
struct Detail {
  @Param @Require
  detailId: string;
  pages: NavPathStack = new NavPathStack();

  aboutToAppear(): void {
    hilog.info(0, 'detail', 'about to appear: '+this.detailId)
  }

  build() {
    NavDestination() {
      Column() {
        Text('detail page: '+this.detailId)
      }
    }
    .title('详情')
    .onReady((context: NavDestinationContext) => {
      this.pages = context.pathStack;
    })
  }
}

routes.json

{
  "routerMap": [
    {
      "name": "detail",
      "pageSourceFile": "src/main/ets/pages/Home.ets",
      "buildFunction": "buildDetail"
    }
  ]
