StreamingWebSocketClient never close

[CorrM]

In StreamingWebSocketClient.CloseDisposeAndClearRequestsAsync

CancellationTokenSource tokenSource = null;
            try
            {
                if (_clientWebSocket != null && (_clientWebSocket.State == WebSocketState.Open || _clientWebSocket.State == WebSocketState.Connecting))
                {
                    tokenSource = new CancellationTokenSource(ConnectionTimeout);

                    await _clientWebSocket.CloseOutputAsync(WebSocketCloseStatus.NormalClosure, "",
                         tokenSource.Token).ConfigureAwait(false);
                    while (_clientWebSocket.State != WebSocketState.Closed && !tokenSource.IsCancellationRequested) ;
                }
            }
            catch { }
            finally
            {
                tokenSource?.Dispose();
            }

This while is CPU eater, use Task.Delay.
The websocket never closed for some reason. (thats make that while go crazy on the CPU)

Expected Behavior

Websocket closed and my CPU are safe

Current Behavior

While loop eat the CPU because websocket state never be Closed (WebSocketState.Closed)

Possible Solution

1. Look for what case the websocket state not updated.
2. Add Task.Delay for 1.0 or 0.5 sec even if the close problem fixed.

Steps to Reproduce

1. call StreamingWebSocketClient.StartAsync()
2. call StreamingWebSocketClient.Dispose() or StreamingWebSocketClient.StopAsync()

Yes that will help, although why is your web socket not disconnecting straight away?
