HarmonyOS 鸿蒙Next：navigation方式路由跳转时页面struct生命周期不触发，仅触发navDestination容器生命周期aboutToAppear、onShow等无效

我的代码是这样的：
@Entry
@Component
struct NavigationPage {
  @Provide pageStack: NavPathStack = new NavPathStack()

  @Builder
  pageMap(name: string) {
    if (name == 'TestComp') {
      TestComp()
    }
  }

  build() {
    Navigation(this.pageStack) {
      Button('TestPage')
      .onClick(() => {
        this.pageStack.pushPath({ name: 'TestComp' })
      })
    }
    .width('100%')
    .height('100%')
    .mode(NavigationMode.Auto)
    .navDestination(this.pageMap)
  }
}

@Preview
@Component
export struct TestComp {
  @Consume pageStack: NavPathStack

  aboutToAppear(): void {
    console.log('aboutToAppear');
  }

  aboutToDisappear(): void {
    console.log('aboutToDisappear')
  }

  build() {
    NavDestination() {
      Column() {
        Text('TestComp')
        .width('100%')
        .height('100%')
        .textAlign(TextAlign.Center)
        .fontSize(30)
      }
      .width('100%')
      .height('100%')
    }
    .onBackPressed(() => {
      this.pageStack.pop()
      return true
    })
  }
}
