Hello

I'm trying to modify the default theme. I've got a directory alongside my application which contains the theme, so I'm importing the distributed files as a plugin, then applying the theme, e.g:

typedoc --plugin ./my-theme --theme custom

The code for my theme is pretty simple, and follows the docs here: https://github.com/TypeStrong/typedoc/blob/master/internal-docs/custom-themes.md

The code (modified, as I think those are slightly out of date):

class MyThemeContext extends DefaultThemeRenderContext {
   // ...
}

class MyTheme extends DefaultTheme {
    private _contextCache?: MyThemeContext;
    override getRenderContext(page) {
        this._contextCache ||= new MyThemeContext(
            this, // <-- changed
			page, // <-- added
            this.application.options,
        );
        return this._contextCache;
    }
}

export function load(app: Application) {
    app.renderer.defineTheme("custom", MyTheme);
}

I kind of expected the theme in this case to be exactly the same as the default one, where I could then override specific parts such as the footer.. However instead the generated docs contain none of the sub-pages (classes, interfaces etc) and no CSS styles.

Is this expected?
