Spring Java generated OpenAPI HTML web page doesn't properly render embedded API docs?

Description

OpenAPI codegen generated API documentation for Spring Java HTML REST API web page appears incomplete. In particular, the model and example code of the YAML specification, whether or not the schema is specified in context or a $ref, is not echoed to the screen.

Swagger-codegen version

3.0.10

Swagger declaration file content or url

This NIH project OpenAPI 3.0 specification:

https://raw.githubusercontent.com/NCATS-Tangerine/NCATS-ReasonerStdAPI/master/API/TranslatorReasonersAPI.yaml

is what we're trying to run through the Spring Java codegen.

If there are some things non-compliant with the OpenAPI 3.0 specification, let me know. However, this specification seems to render well in the Swagger editor (https://editor.swagger.io/?url=https://raw.githubusercontent.com/NCATS-Tangerine/NCATS-ReasonerStdAPI/master/API/TranslatorReasonersAPI.yaml).

It would be helpful to have a reliable Spring Java code generator again by fixing this and other recent related issues (https://github.com/swagger-api/swagger-codegen/issues/9644, https://github.com/swagger-api/swagger-codegen/issues/9645, https://github.com/swagger-api/swagger-codegen/issues/9646) posted.

The issue provides the TranslatorReasonersAPI.yaml specification and the Swagger Editor URL, but names no repository files or tests. Start by generating the Spring Java HTML documentation with swagger-codegen 3.0.10 and compare its missing model and example output with the Swagger Editor rendering. Done means embedded API documentation renders those model and example details for both inline schemas and $ref schemas.
