[Windows] Toolkit-DSL: Components not rendering

Hi

I'm relatively tempted in trying to create a "bigger" CLI application using TamboUI. But There are a couple of steps I'm either missing or that are not working as I'd expected them to do.

Simple app:

fun main() {
    TestApp().run()
}

// extended example with custom components and config
class TestApp : ToolkitApp() {

    override fun configure(): TuiConfig? {
        return TuiConfig.builder()
            // .mouseCapture(true)
            // .hideCursor(true)
            .fpsOverlay(true)
            .tickRate(50.milliseconds.toJavaDuration()) // 16 for 60 FPS, 33 for 30 FPS, 50 for 20 FPS
            .build()
    }

    override fun render(): Element? {
        return panel(
            "Hello",
            text("Welcome to TamboUI DSL!").bold().cyan(),
            object : Component<Nothing>() {
                override fun render(): Element? {
                    return text("This is a placeholder component").bold().cyan()
                }
            }.id("placeholder-component"),
            column(
                Button("Click me!").id("button-1"),
                CounterComponent().id("counter-1")
            ),
            spacer(),
            text("Press 'q' to quit").dim()
        ).rounded()
    }
}

// my own attempts
class Button(
    private val title: String,
    private val handleKeyEvent: KeyEvent.() -> EventResult = { EventResult.UNHANDLED }
) : Component<Button>() {
    override fun preferredSize(): Size? {
        return Size.heightOnly(3)
    }

    override fun render(): Element =
        panel(text(title))
            .rounded()
    // .borderColor(if (isFocused) Color.GREEN else Color.GRAY)
    // .focusable(true)
    // .onKeyEvent { if (isFocused) it.handleKeyEvent() else EventResult.UNHANDLED }

    override fun handleKeyEvent(event: KeyEvent, focused: Boolean): EventResult? {
        if (isFocused && EventResult.HANDLED == event.handleKeyEvent()) {
            return EventResult.HANDLED
        }
        return super.handleKeyEvent(event, focused)
    }
}

// from the examples
class CounterComponent : Component<CounterComponent>() {
    var count = 0

    @OnAction(Actions.MOVE_UP)
    fun increment(event: Event) {
        count++
    }

    override fun render(): Element {
        return text("Count: " + count)
    }
}

Regardless whether I use the default config, Java 21 and JLine- or 25 and Panama-backend, the components are never displayed. I tried a more complex UI (without custom components) where on the other hand I falied to properly attach Key handlers.

So basically it's working 50% or more but never to the extend I hoped.

Do you see anything wrong the little app or do you have some general suggestions what I should change?

Kind regards Daniel
