HarmonyOS 侧滑动屏幕边缘弹框会消失，如何解决

代码如下：

/**
 * 利用弹框组件构造隐私协议弹框
 */
dialogController: CustomDialogController | null = new CustomDialogController({
  builder: CustomContentDialog({
    contentBuilder: () => {
      this.constructPrivacyInfo();
    },
    buttons: [{
      value: $r("app.string.privacy_dialog_cancel"),
      buttonStyle: ButtonStyleMode.TEXTUAL,
      action: () => {
        this.onDialogCancel();
        // 如果宿主是uiextension，隐私弹框则是模系统，需要自己关弹框
        this.closeDialogWithMotion('close privacy dialog due to touching cancel');
        console.info('Callback when the button is clicked')
      }
    }, {
      value: $r("app.string.privacy_dialog_agree"),
      buttonStyle: ButtonStyleMode.TEXTUAL,
      action: () => {
        this.closeDialogWithMotion('close privacy dialog due to touching agree');
        this.onDialogAgree();
      }
    }],
  }),
  autoCancel: false,
});
