Actual UI Behavior

The option_cross_margin_params property is shows correctly in the properties of the response. However it is skipped in the rendered response example to the right-hand side.

Expected UI Behavior

This show in the properties, so I would expect the example to contain this property. I think this might be related or a duplicate of this issue. In any case, I did validate the spec with openAPI tooling and this shows properly.

Steps to Reproduce

1. Use a spec like the one provided
2. If you remove the $ref elements from imf/mmf and input strings the render works
3. Adding the $ref elements back you will no longer see the response example
