[🐛 Bug]: Multiple Async/Fetch Errors Being Thrown when Trying to Transform Network Requests and Add Headers

[ascendantofrain]

What happened?

When trying to set up network interception using the NetworkRequestHandler, I am receiving multiple different errors being thrown as a website is loaded.

Errors include but are not limited to:
System.InvalidOperationException: A command response was not received: Fetch.getResponseBody
System.InvalidOperationException: There is already one outstanding 'SendAsync' call for this WebSocket instance. ReceiveAsync and SendAsync can be called simultaneously, but at most one outstanding operation for each of them is allowed at the same time.

How can we reproduce the issue?

var requestHandler = new NetworkRequestHandler
{
    RequestMatcher = request => true,
    RequestTransformer = req =>
    {
        if (!req.Headers.ContainsKey("xxx"))
            req.Headers.Add("xxx", "xxx");
                
        return req;
    }
};

var driver = new ChromeDriver();

var networkInterceptor = driver.Manage().Network;
networkInterceptor.AddRequestHandler(requestHandler);
        
await networkInterceptor.StartMonitoring();

// load a site and do stuff

await networkInterceptor.StopMonitoring()

Operation is not valid due to the current state of the object.
