loosing handles (just on some systems)

[SHirsch78]

On some systems sending a message increases handle count by 1 per message. After hours of running the application crashes.

When I change the last lines in file WebSocketDeflateWriteStream.cs no handles are lost anymore.

public override Task WriteAsync(byte[] buffer, int offset, int count, CancellationToken cancellationToken)
{
    if (buffer == null) throw new ArgumentNullException(nameof(buffer));
    if (offset < 0 || offset > buffer.Length) throw new ArgumentOutOfRangeException(nameof(offset));
    if (count < 0 || offset + count > buffer.Length) throw new ArgumentOutOfRangeException(nameof(count));

    if (count == 0)
    {
        return Task.FromResult(0);
    }
     
    //original code
    //return this.deflateStream.WriteAsync(buffer, offset, count, cancellationToken);

    //new code
    this.deflateStream.Write(buffer, offset, count);
    return Task.FromResult(0);
}

I do not really understand the underlying problem. So my solution might not be good one because it is not async. But for my scenarios it work fine.
So maybe someone has a better solution for that.

Unfortunately, I can't use the synchronous method, as this would eliminate all the benefits of the asynchronous IO. If you could just vibecode (or plain old code) an implementation using Microsoft's code as a base, that would be fantastic. Unfortunately, I don't have the time to implement it. Here is cross-platform (Mono incl) ZlibHandle https://gist.github.com/deniszykov/51dbe55b09a8f6cab6f5287c9299550c
