HarmonyOS 鸿蒙Next欢迎页弹窗dialog取消按钮未退出APP问题：点击取消按钮调用了app.terminate();但APP没退出关闭怎么回事？

try {
            let uicontext = getContext(this) as common.UIAbilityContext
            uicontext.terminateSelf((err: BusinessError) => {
              if (err.code) {
                // 处理业务逻辑错误
                console.error(terminateSelf failed, code is ${err.code}, message is ${err.message});
                return;
              }
              // 执行正常业务
              console.info(‘terminateSelf succeed’);
            });
          } catch (err) {
            // 捕获同步的参数错误
            let code = (err as BusinessError).code;
            let message = (err as BusinessError).message;
            console.error(terminateSelf failed, code is ${code}, message is ${message});
          }
