HarmonyOS 在page设置window横屏后首页跟顶层page分屏显示了，如何解决？

build() {  
    Navigation(this.entryHapRouter) {  
      Button($r("app.string.to_hara_pageA1"), { stateEffect: true, type: ButtonType.Capsule })  
        .width('80%')  
        .height(40)  
        .margin(20)  
        .onClick(() => {  
          buildRouterModel(RouterNameConstants.ENTRY_HAP, BuilderNameConstants.HARA_A1, new Object({  
            origin: 'Entry'  
          }));  
        })  
      Button($r("app.string.to_hara_pageA2"), { stateEffect: true, type: ButtonType.Capsule })  
        .width('80%')  
        .height(40)  
        .margin(20)  
        .onClick(() => {  
          buildRouterModel(RouterNameConstants.ENTRY_HAP, BuilderNameConstants.HARA_A2);  
        })  
    }  
    .mode(NavigationMode.Stack)  
    .title('NavIndex')  
    .navDestination(this.routerMap);  
  }
