Documentation Failing to Render oneOf Request Schema

[hskrasek]

Describe the bug
When documenting an API I ran into a bug where the Redocly CLI build docs, or the open source HTML Element properly renders the code examples for a oneOf/discriminator requestBody but fails to present the schema, properties, and descriptions.

Expected behavior
I expect the schema definition, with properties and description.

Minimal reproducible OpenAPI snippet(if possible)

        The tagId is unique to your publisher account and authorizes you to send leads for particular services.
        tagID=204670250 is used only for the Staging environment. Once we confirm stage tests and you move to using the production API,
        this value must be replaced with the tagID value given to you by your account manager.
