How to record HTML from a fake console

[SimonRev]

In my app, I am adding an option to update an HTML page.

I have figured out how to use the Recorder to capture the output my program emits and produce HTML output.

However, I would like to not display to the screen when I want to produce HTML. I have figured out how to make a fake IAnsiConsole and can see the ANSI output appear in the StringWriter of my fake console, but whenever I try to get the recorder to emit the HTML, it just produces a blank "pre" HTML element.

void GenHtml() {
    var fakeConsoleOutput = new FakeConsoleOutput();
    var fakeConsole = AnsiConsole.Create(new AnsiConsoleSettings
    {
        Ansi = AnsiSupport.Yes,
        Out = fakeConsoleOutput,
        Interactive = InteractionSupport.No,
        ColorSystem = ColorSystemSupport.TrueColor,
    });
    using var fakeRecorder = new Recorder(fakeConsole);
    discover.PrintDiscoveryTable(fakeConsole, devices, jsonStdErr);
    string fakeHtml = fakeRecorder.ExportHtml();;

    AnsiConsole.Record();
    discover.PrintDiscoveryTable(AnsiConsole.Console, devices, jsonStdErr);
    string realHtml = AnsiConsole.ExportHtml();;
}


class FakeConsoleOutput : IAnsiConsoleOutput
{
    public TextWriter Writer { get; } = new StringWriter();
    public bool IsTerminal => false;
    public int Width => 220;
    public int Height => 100;
    public void SetEncoding(Encoding encoding) {}
}

Any thoughts how I can get HTML from my fake console
