Model attributes of type null not rendered

[jschaefer77]

Some of our models have attribute types like string and in addition null.

Context

Current Behavior

In Stoplight Studio type string and null is rendered in preview mode,

But not in standalone version of elements. Only type string is shown.

Expected Behavior

Both types (e.g. string and null) should be rendered.

Possible Workaround/Solution

No workaround possible

Steps to Reproduce

1. Create a model with one attribute. Attribute type set to string and null.
2. Check how the attribute is rendered in elements.
