HarmonyOS鸿蒙Next中ARK UI自定义弹窗嵌套，第二层弹窗使用this.controller.close()报错

如题，在弹窗嵌套（CustomDialog打开CustomDialog），第二层被打开的弹窗无法使用this.controller.close()，报错信息如下：

[phone][Ace  ERROR] 02/28 22:24:43 22716 [qjs_utils.cpp(JsStdDumpErrorAce)-(0)] [Engine Log] [DUMP] TypeError: cannot read property 'close' of undefined

代码如下：

@CustomDialogstruct myCustomDialog {
  controller: CustomDialogController
  private text: string
  private openNextDialog() {
    var DeleteCustomDialogController: CustomDialogController = new CustomDialogController({
      builder: myCustomDialog({ text: '弹窗2' })
    })
    DeleteCustomDialogController.open()
  }
  build() {
    Column() {
      Text(this.text)
        .fontSize(30)
      Row() {
        Button('取消')
          .onClick(() => {
            this.controller.close()
          })
        Button('打开')
          .onClick(() => {
            this.controller.close()
            this.openNextDialog()
          })
      }
    }
  }
}
@Entry
@Componentstruct CustomDialogUser {
  DeleteCustomDialogController: CustomDialogController = new CustomDialogController({
    builder: myCustomDialog({ text: '弹窗1' })
  })
  build() {
    Column() {
      Button('test')
        .onClick(() => {
          this.DeleteCustomDialogController.open()
        })
    }.width('100%').margin({ top: 5 })
  }
}
