CircleHitbox doesn't scale

[gnarhard]

What happened?

When scaling a CircleHitbox, the debug lines make it look like it scaled correctly, but collisions don't register in the bounds because the hit box didn't scale.

What do you expect?

CircleHitbox should scale.

How can we reproduce this?

What steps should take to fix this?

Do have an example of where the bug occurs?

void main() {
  runApp(
    const MaterialApp(
      home: GameWidget.controlled(
        gameFactory: _MyGame.new,
      ),
    ),
  );
}

class _MyGame extends FlameGame with HasCollisionDetection {
  @override
  Future<void> onLoad() async {
    camera = CameraComponent.withFixedResolution(width: 640, height: 360);

    await world.add(
      _MyCircleComponent(BasicPalette.white.color.withAlpha(100),
          BasicPalette.red.color.withAlpha(100),
          radius: 20, anchor: Anchor.center)
        ..add(
          MoveByEffect(
            Vector2(50, 0),
            EffectController(
              duration: 2,
              alternate: true,
              infinite: true,
            ),
          ),
        ),
    );

    await world.add(
      _MyCircleComponent(
        BasicPalette.green.color.withAlpha(100),
        BasicPalette.blue.color.withAlpha(100),
        radius: 20,
        anchor: Anchor.center,
        position: Vector2(80, 0),
      )..add(
          ScaleEffect.by(
            Vector2.all(2),
            EffectController(
              duration: 2,
              alternate: true,
              infinite: true,
            ),
          ),
        ),
    );
  }
}

class _MyCircleComponent extends CircleComponent with CollisionCallbacks {
  final Color color;
  final Color hitColor;

  _MyCircleComponent(this.color, this.hitColor,
      {super.position, super.radius, super.anchor});

  @override
  Future<void> onLoad() async {
    super.onLoad();
    paint.color = color;
    await add(CircleHitbox()..debugMode = true);
  }

  @override
  void onCollisionStart(
      Set<Vector2> intersectionPoints, PositionComponent other) {
    paint.color = hitColor;
    super.onCollisionStart(intersectionPoints, other);
  }

  @override
  void onCollisionEnd(PositionComponent other) {
    paint.color = color;
    super.onCollisionEnd(other);
  }
}
