Display type(s) when using `allOf`

When using just $ref the referenced schema is displayed.

first:
  $ref: '#/components/schemas/SomeType'

But when using allOf the original schemas aren't displayed any more.

second:
  allOf:
    - $ref: '#/components/schemas/SomeType'
third:
  allOf:
    - $ref: '#/components/schemas/SomeType'
    - $ref: '#/components/schemas/SomeOtherType'

Describe the solution you'd like

It would be nice if the schema is also displayed when using allOf.

Start with the supplied OpenAPI definition and compare Swagger UI's rendering of the direct $ref property with the properties using allOf. Trace the schema display path for these two cases and verify that referenced types appear for both single- and multi-reference allOf schemas.
