在打开一个自定义DialogA之后，在DialogA的回调中，关闭DialogA, 再打开DialogB，结果DialogB无法打开

private dialogController?: CustomDialogController = new CustomDialogController({  
  builder: AgreementPolicyDialog({  
    customAgreement: this.AgreementPolicyContent,  
    onConfirm: this.onConfirm,  
    loadingDialogController: this.loadingDialogController  
  }),  
  alignment: DialogAlignment.Center,  
  customStyle: true,  
  autoCancel: true  
})

loadingDialogController: CustomDialogController  
controller: CustomDialogController
