HarmonyOS TextInput在弹框消失后焦点自动获取问题

可以参考如下demo:

@Entry
@Component
struct TextInputExample {
  @State PassWordSrc1: Resource = $r('app.media.startIcon')
  @State PassWordSrc2: Resource = $r('app.media.background')
  @State TextError: string = ''
  @State Text: string = ''
  @State NameText: string = 'test'
  controller: TextInputController = new TextInputController()
  controller1: TextInputController = new TextInputController()
  @Builder itemEnd() {
    Select([{ value: 'KB' },
      { value: 'MB' },
      { value: 'GB' },
      { value: 'TB', }])
      .height("48vp")
      .borderRadius(0)
      .selected(2)
      .align(Alignment.Center)
      .value('MB')
      .font({ size: 20, weight: 500 })
      .fontColor('#182431')
      .selectedOptionFont({ size: 20, weight: 400 })
      .optionFont({ size: 20, weight: 400 })
      .backgroundColor(Color.Transparent)
      .responseRegion({ height: "40vp", width: "80%", x: '10%', y: '6vp' })
      .onSelect((index: number) => {
        console.info('Select:' + index)
      })
  }
  build() {
    Column({ space: 20 }) {
      // 下划线模式
      TextInput({ controller: this.controller1, placeholder: 'underline style' })
        .showUnderline(true)
        .width(380)
        .height(60)
        .showUnit(this.itemEnd)
      Text(`用户名：${this.Text}`)
        .width('95%')
      TextInput({controller: this.controller, placeholder: '请输入用户名', text: this.Text })
        .showUnderline(true)
        .width(380)
        .showError(this.TextError)
        .onChange((value: string) => {
          this.Text = value
        })
        .onSubmit(() => { // 用户名不正确会清空输入框和用户名并提示错误文本
          if (this.Text == this.NameText) {
            this.TextError = ''
          } else {
            this.TextError = '用户名输入错误'
            this.Text = ''
          }
        })
      Button("点击出现弹窗").width(100).height(100)
        .onClick(() => {
          // 关闭自定义键盘
          this.controller.stopEditing()
          this.controller1.stopEditing()
          AlertDialog.show(
            {
              title: 'title',
              message: 'text',
              autoCancel: true,
              alignment: DialogAlignment.Bottom,
              offset: { dx: 0, dy: -20 },
              gridCount: 3,
              confirm: {
                value: 'button',
                action: () => {
                  console.info('Button-clicking callback')
                }
              },
              cancel: () => {
                console.info('Closed callbacks')
              }
            }
          )
        })
        .backgroundColor(0x317aff)
    }.width('100%')
  }
}
