Unable to scroll in frame (based on minor example adaptation)

[mavam]

I tried to perform a small adaptation of the example that renders checkboxes in a frame. I only exchanged Checkbox for Slider, but then scrolling doesn't work anymore.

(This is an attempt to simplify a problem with frame in a larger application I am writing.)

int main(int argc, const char* argv[]) {
  static std::array<int, 30> values;
  auto container = Container::Vertical({});
  for (size_t i = 0; i < 30; ++i)
    container->Add(Slider("Value:", &values[i], 0, 100, 1));
  auto renderer = Renderer(container, [=] {
    return container->Render() | vscroll_indicator | frame | size(HEIGHT, LESS_THAN, 10) | border;
  });
  auto screen = ScreenInteractive::FitComponent();
  screen.Loop(renderer);
  return 0;
}

What is the missing ingredient?
