Azure Web Apps + AAD B2C登出异常：点击登出后仍保持登录

我开发了一个简单的Razor WebAssembly应用，采用Azure Active Directory B2C作为用户认证与授权的可信源。登录流程正常：访问StaticWebApp的URL时，会按预期跳转到登录页面，输入用户名和密码登录成功后，应用主页会显示当前登录用户的邮箱。但点击登出按钮后，虽按预期跳转到登录页面，实际并未完成登出操作——再次访问应用时，无需重新登录就会直接显示已登录状态。

我的staticwebapp.config.json配置 #

                }
            }
        }
    }
}

主页使用的LoginDisplay Razor组件代码 #

<AuthorizeView>
    <Authorized>
        Hello @context.User?.Identity?.Name!
        <a href="/logout">Log out</a>
    </Authorized>
    <NotAuthorized>
        <a href="/login">Log in</a>
    </NotAuthorized>
</AuthorizeView>

补充信息 #

• 用户流中「Require ID Token in logout requests」属性已设置为True
• 已注册应用的「Front-channel logout URL」设置为https://{NAME}.azurestaticapps.net/.auth/logout

请问我遗漏了什么配置或步骤？
