If you await a request when the client is disconnected it hangs indefinitely, is this intended?

Hi,

I have an unstable connection so it can disconnect at any time, but SteamKit doesn't detect it's actually lost connection to the steam servers for ~30 seconds after my connection disconnects. This can cause my app to send a request when it's already lost connection, and if I use await instead of the callback handler this causes an infinite hang.

Can be reproduced with this (admittedly convoluted example):

static async Task Test()
{
    bool isLoggedIn = false;
    var steamClient = new SteamClient();
    var manager = new CallbackManager(steamClient);
    manager.Subscribe<SteamClient.ConnectedCallback>(callback => 
    {
        Console.WriteLine("Connected");
        steamClient.GetHandler<SteamUser>()!.LogOnAnonymous();
    });
    manager.Subscribe<SteamClient.DisconnectedCallback>(callback => Console.WriteLine("Disconnected"));
    manager.Subscribe<SteamUser.LoggedOnCallback>(callback => 
    {
        isLoggedIn = true;
        Console.WriteLine("Logged on");
    });
    manager.Subscribe<SteamUser.LoggedOffCallback>(callback => Console.WriteLine("Logged off"));

    manager.Subscribe<SteamApps.PICSProductInfoCallback>(callback => Console.WriteLine(JsonConvert.SerializeObject(callback)));

    steamClient.Connect();
    for (int i = 1; i < 10_000; i++)
    {
        manager.RunWaitCallbacks(TimeSpan.FromSeconds(1));
        if (i % 19 == 0) steamClient.Disconnect();
        if (i % 10 == 0 && isLoggedIn)
        {
            Console.WriteLine(steamClient.IsConnected);
            var appRequest = new SteamApps.PICSRequest(1245620, 0);
            var app = await steamClient.GetHandler<SteamApps>()!.PICSGetProductInfo(app: appRequest, package: null, metaDataOnly: false);
            // ^^ On the 2nd call, when the connection is disconnected this hangs indefinitely, of course, in this example I know it's disconnected, because steamClient.IsConnected is false, but if my internet hard disconnects IsConnected is still true when the call fires
            Console.WriteLine(JsonConvert.SerializeObject(app));
        }
    }
}

f I use a callback (SteamApps.PICSProductInfoCallback) it's OK but async/await is much more convenient. Is there any way to get it to timeout instead of just hanging indefinitely? Thanks
