Example SPA project container using ContainerV1 doesn't show any parsys

Hi,

while testing the **SPA** example projects I realised that the container component does not show any Parsys, see the screenshot. Wanted to know if this is by definition or an error.

Also, both options it allows **[Simple, Responsive]**, render essentially the same HTML, what is the actual purpose of this component then?


Start by reproducing the issue in the SPA example projects with the ContainerV1 component and compare the Simple and Responsive options. Determine whether the missing Parsys is intentional and document or correct the component behavior so its purpose and expected HTML are clear.
