HarmonyOS 鸿蒙Next Tabs里的组件生命周期(onPageShow)不回调

求助各位大佬！

[@Entry](/user/Entry)
[@Component](/user/Component)
struct MainPage {
build() {
  Tabs({ barPosition: BarPosition.End, controller: this.tabsController }) {
    TabContent() {
      MyPage()
    }
    .tabBar(this.TabBuilder('我的', 3, $r('app.media.ic_tab_user_sel'), $r('app.media.ic_tab_user_nor')))

  }

[@Entry](/user/Entry)
[@Component](/user/Component)
export struct MyPage {}

主页面以及MyPage的onPageShow在每次切换tab都不会走到
onPageShow() {
  this.requestMineUserInfo()
}
