.NET 8下System.Net.WebSockets无法持续接收消息问题咨询

我在使用.NET 8的System.Net.WebSockets编写程序时遇到异常情况：客户端发送的第一条消息能被服务端成功接收，但后续发送的消息无法让ReceiveAsync持续返回。

以下是无法正常运行的简化示例代码：

[ApiController]
[Route("[controller]")]
public class WebSocketController : ControllerBase
{
    [HttpGet]
    public async Task Get()
    {
        if (HttpContext.WebSockets.IsWebSocketRequest)
        {
            using var webSocket = await HttpContext.WebSockets.AcceptWebSocketAsync();
            await ReceiveMessages(webSocket);
        }
        else
        {
            HttpContext.Response.StatusCode = StatusCodes.Status400BadRequest;
        }
    }

    private static async Task ReceiveMessages(WebSocket webSocket)
    {
        WebSocketReceiveResult receiveResult;
        var buffer = new byte[1];
        do
        {
            receiveResult = await webSocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);
        } while (!receiveResult.CloseStatus.HasValue);

        await webSocket.CloseAsync(
            receiveResult.CloseStatus.Value,
            receiveResult.CloseStatusDescription,
            CancellationToken.None);
    }
}

但如果在每次接收消息后添加向客户端发送消息的代码，服务端就能正常接收所有客户端消息：

private static async Task ReceiveMessages(WebSocket webSocket)
{
    WebSocketReceiveResult receiveResult;
    var buffer = new byte[1];
    do
    {
        receiveResult = await webSocket.ReceiveAsync(new ArraySegment<byte>(buffer), CancellationToken.None);
        await webSocket.SendAsync(new ArraySegment<byte>(buffer), WebSocketMessageType.Text, true, CancellationToken.None);
    } while (!receiveResult.CloseStatus.HasValue);

    await webSocket.CloseAsync(
        receiveResult.CloseStatus.Value,
        receiveResult.CloseStatusDescription,
        CancellationToken.None);
}

我的使用场景不需要每次接收消息都回复客户端。查阅RFC 6455和微软官方文档后，我认为第一段代码应该可以正常运行。请问我是对WebSocket或System.Net.WebSockets存在理解误区，还是该组件存在bug？

补充：以下是我的Program.cs代码，仅在默认ASP.NET Core Web API模板基础上添加了WebSocketMiddleware的使用：

public class Program
{
    public static void Main(string[] args)
    {
        var builder = WebApplication.CreateBuilder(args);

        // Add services to the container.

        builder.Services.AddControllers();
        // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
        builder.Services.AddEndpointsApiExplorer();
        builder.Services.AddSwaggerGen();

        var app = builder.Build();

        // Configure the HTTP request pipeline.
        if (app.Environment.IsDevelopment())
        {
            app.UseSwagger();
            app.UseSwaggerUI();
        }

        app.UseHttpsRedirection();

        app.UseAuthorization();

        app.UseWebSockets();

        app.MapControllers();

        app.Run();
    }
}
