钉钉自定义选人好像有bug

先运行自定义选人控件(单选)
dd.biz.customContact.choose({
                        title : '选择签发人',
                        users : arr,
                        corpId : '',
                        isShowCompanyName : true,
                        onSuccess : function(data) {

                        },
                        onFail : function(err) {
                            alert(JSON.stringify(err));
                        }
                    });
这个时候不选人,点击右上角的取消然后在运行企业通讯录选人
dd.biz.contact.choose({
                  startWithDepartmentId:0,
                  multiple: false,
                  users: [],
                  corpId:,
                  max: 1,
                  onSuccess: function(data) {


                  },
                  onFail : function(err) {
                      alert(JSON.stringify(err));
                  }
                });
随便选中一个人之后,返回data,会同时执行原来自定义选人的onSuccess: function(data){}和企业通讯录选人的onSuccess: function(data){}
