showObjectSchemaExamples doesn't render examples for object properties

[kai687]

Describe the bug

With the option showObjectSchemaExamples set to true, I only see Example: [object Object] in the description for objects. Other examples, like strings, render fine.

Used redoc@2.2.0.

Expected behavior

I expected the provided examples for properties of type object to be rendered out.

Additional context

While for objects with defined properties, I can just provide the examples with the properties,
but for objects that accept additionalProperties, it'll be difficult.
