HarmonyOS 为什么状态栏的显隐切换，高度值并没有实时生效？会导致下一个界面的标题和状态栏重叠

参考Demo如下：

Index页

import { router } from '@kit.ArkUI'
@Entry
@Component
struct Index {
  build() {
    Column(){
      Button($r('app.string.Button_text')).onClick((event: ClickEvent) => {
        router.pushUrl({
          url: 'pages/Test'
        })
      })
    }
  }
}

Test页

import { router, window } from '@kit.ArkUI'
import I18n from '@ohos.i18n';
@Entry
@Component
struct Test {
  aboutToAppear(): void {
    window.getLastWindow(getContext(this)).then((win)=>{
      win.setWindowSystemBarEnable([])
      console.info('状态栏高度：'+
      win.getWindowAvoidArea(window.AvoidAreaType.TYPE_SYSTEM)
        .topRect
        .height
      )
    })
  }
  onPageHide(): void {
    window.getLastWindow(getContext(this)).then((win)=>{
      win.setWindowSystemBarEnable(['status','navigation'])
      console.info('状态栏高度：'+
      win.getWindowAvoidArea(window.AvoidAreaType.TYPE_SYSTEM)
        .topRect
        .height
      )
    })
    try {
      I18n.System.setAppPreferredLanguage('en-Latn-US');
    } catch (err) {
      console.error(`Failed to set the system locale. message:${err.message}, code:${err.code}`);
    }
  }
  build() {
    Column(){
      Column(){
        Button('返回').onClick((event: ClickEvent) => {
          router.back()
        })
      }
    }
  }
}
