Content & configuration

Example Swagger/OpenAPI definition:

components:
  schemas:
    Order:
      type: object
      properties:
        testMap:
          type: object

Describe the bug you're encountering

Per https://swagger.io/docs/specification/data-models/dictionaries/

Examples of Dictionary Contents
You can use the example keyword to specify sample dictionary contents:

type: object
additionalProperties:
type: string
example:
en: Hello!
fr: Bonjour!

UI does not render any of these examples in the schema section, it only shows { < * >: String }

To reproduce...

Steps to reproduce the behavior:

1. Go to editor.swagger.io
2. Add a dictionary with examples to a component schema
3. Look at render
4. See no examples in the schemas section.

Expected behavior

Component schema preview shows examples in-line.

Screenshots

Additional context or thoughts

Reproduce the issue in editor.swagger.io with the provided OpenAPI component schema and inspect the schema rendering path for object dictionaries with additionalProperties and example values. Done means the Schemas section displays the supplied en-us and fr example contents inline instead of only showing { < * >: String }.
