Blazor HubConnectionBuilder Timeouts

Does this work for anyone?

        hubConnection = new HubConnectionBuilder()
            .WithUrl(Navigation.ToAbsoluteUri($"/chatroomhub"))
            .WithServerTimeout(TimeSpan.FromSeconds(30))
            .WithKeepAliveInterval(TimeSpan.FromSeconds(15))
            .Build();

        hubConnection = new HubConnectionBuilder()
            .WithUrl(Navigation.ToAbsoluteUri($"/chatroomhub"))
            .WithServerTimeout(TimeSpan.FromSeconds(30))
            .WithKeepAliveInterval(TimeSpan.FromSeconds(15))
            .Build();

I can navigate away from the page for minutes and nothing happens. Connection is never closed...

All I want is for the server to time out, after X seconds of inactivity. Only way I could find to resolve this was by setting in Program.cs

builder.Services.AddSignalR().AddHubOptions<ChatRoomHub>(options =>
{
    options.KeepAliveInterval = TimeSpan.FromSeconds(60);
});

builder.Services.AddSignalR().AddHubOptions<ChatRoomHub>(options =>
{
    options.KeepAliveInterval = TimeSpan.FromSeconds(60);
});

And in the Hub

 hubConnection = new HubConnectionBuilder()
     .WithUrl(Navigation.ToAbsoluteUri($"/chatroomhub"))
     .WithServerTimeout(TimeSpan.FromSeconds(30))
     .Build();

 hubConnection = new HubConnectionBuilder()
     .WithUrl(Navigation.ToAbsoluteUri($"/chatroomhub"))
     .WithServerTimeout(TimeSpan.FromSeconds(30))
     .Build();

So, intentionally setting the KeepAliveInterval to be longer than the ServerTimeout. If i don't specify the KeepAliveInterval at all, then the server NEVER times out. This does not seem right to me...
