HarmonyOS 鸿蒙Next 关于在热启动跳转的时候，出现两个页面的问题

1.代码

// AbilityB
import { AbilityConstant, UIAbility, Want } from '@kit.AbilityKit';
import { Router, UIContext, window } from '@kit.ArkUI';

export default class ReceiveStartAbilityForTwoComponent extends UIAbility {
  private mWant: Want | undefined
  private uiContent: UIContext | undefined

  onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
    this.mWant = want
  }

  onWindowStageCreate(windowStage: window.WindowStage): void {
    let url = 'pages/s14_startAbility/S2_StartAbility'
    if (this.mWant?.parameters?.type === 'S2') {
      url = 'pages/s14_startAbility/S3_StartAbility'
    }
    windowStage.loadContent(url, (error, data) => {
      if (error.code) {
        return
      }
      windowStage.getMainWindow((error, data) => {
        if (error.code) {
          return
        }
        this.uiContent = data.getUIContext()
      })
    })
  }

  onNewWant(want: Want, launchParam: AbilityConstant.LaunchParam): void {
    let url = 'pages/s14_startAbility/S2_StartAbility'
    if (want?.parameters?.type === 'S2') {
      url = 'pages/s14_startAbility/S3_StartAbility'
    }
    if (this.uiContent) {
      const router: Router = this.uiContent.getRouter()
      router.pushUrl({
        url: url
      })
    }
  }
}

//Ability B的页面
@Entry
@Component
struct StartAbilityS3 {

  build() {
    Column () {
      Text('我是第二个页面')
    }
  }
}

@Entry
@Component
struct StartAbilityS2 {

  build() {
    Column () {
      Text('我是第二个页面')
    }
  }
}

// Ability A 的页面
import { common, Want } from '@kit.AbilityKit'

@Entry
@Component
struct StartAbilityS1 {
  private context = getContext(this) as common.UIAbilityContext

  build() {
    Column () {
      Button('跳转第一个页面').onClick((event: ClickEvent) => {
        const want: Want = {
          bundleName: 'com.example.example',
          abilityName: 'ReceiveStartAbilityForTwoComponent',
          parameters: {
            type: 'S1'
          }
        }
        this.context.startAbility(want)
      }).margin(10)

      Button('跳转第二个页面').onClick((event: ClickEvent) => {
        const want: Want = {
          bundleName: 'com.example.example',
          abilityName: 'ReceiveStartAbilityForTwoComponent',
          parameters: {
            type: 'S2'
          }
        }
        this.context.startAbility(want)
      }).margin(10)
    }
  }
}

2. 问题

在第一次点击的时候，能进行正常的跳转，然后按返回键，返回到 AbilityA，再次点击按钮的时候，进入ReceiveStartAbilityForTwoComponent，按返回键，发现 S2 和 S3的页面都出现了，最终显示的是S3，按返回键，显示S2，再按一次返回键才会返回 AbilityA 的页面
