Request body from example is not showing property

I have the following schema that we are using:

 "RenderingDomainRequest" : {
        "title" : "A Rendering Instruction Request",
        "required" : [ "instructionId", "type" ],
        "type" : "object",
        "properties" : {
          "type" : {
            "title" : "The rendering instruction type",
            "type" : "string",
            "description" : "Rendering Type",
            "enum" : [ "CREATIVE_EXTENSION", "EXTENSION", "AD_PARAMETERS" ]
          },
          "instructionId" : {
            "maxLength" : 50,
            "minLength" : 1,
            "type" : "string",
            "description" : "The instruction Id string",
            "example" : "l360_head"
          }
        },
        "discriminator" : {
          "propertyName" : "type",
          "mapping" : {
            "AD_PARAMETERS" : "#/components/schemas/AdParametersRenderingDomain",
            "CREATIVE_EXTENSION" : "#/components/schemas/CreativeExtensionRenderingDomain",
            "EXTENSION" : "#/components/schemas/ExtensionRenderingDomain"
          }
        },
        "oneOf" : [ {
          "$ref" : "#/components/schemas/CreativeExtensionRenderingDomain"
        }, {
          "$ref" : "#/components/schemas/ExtensionRenderingDomain"
        }, {
          "$ref" : "#/components/schemas/AdParametersRenderingDomain"
        } ]
      }

where we have instructionId and type as properties in this parent class and body in the child(discriminated) classes(AdParametersRenderingDomain).

However, when a method uses the RenderingDomainRequest as a request body, I can see it being described correctly based on the discriminator type:

But in the rendering section, the property instructionId is missing from the example request sample:

Furthermore, switching between the discriminated types is not working: the first type is always rendered.

I am using redoc@v2.0.0-rc.40 standalone version.

Reproduce the issue in Redoc v2.0.0-rc.40 using the provided RenderingDomainRequest schema and its discriminated child schemas. Investigate request-body example rendering and discriminator type switching; done means the example includes instructionId and each discriminator choice renders the corresponding child type.
