Enum in allof does not show combobox

[oto313]

Describe the bug

I have parameter of GET method in openapi.json file:

 {
            "name": "Status",
            "in": "query",
            "schema": {
              "nullable": true,
              "allOf": [
                {
                  "$ref": "#/components/schemas/TestBatchStatus"
                }
              ]
            }
          }

Here is definition of TestBatchStatus type

 "TestBatchStatus": {
        "type": "string",
        "description": "",
        "x-enumNames": [
          "Enqueued",
          "Running",
          "Completed",
          "Cancelled"
        ],
        "enum": [
          "Enqueued",
          "Running",
          "Completed",
          "Cancelled"
        ]
      },

this renders the following output in mdx api field (decoded from Base64 GZip format)

{
      "name": "Status",
      "in": "query",
      "schema": {
        "nullable": true,
        "allOf": [
          {
            "type": "string",
            "description": "",
            "x-enumNames": ["Enqueued", "Running", "Completed", "Cancelled"],
            "enum": ["Enqueued", "Running", "Completed", "Cancelled"],
            "title": "TestBatchStatus"
          }
        ]
      }
    },

Expected behavior

It should show combobox where you can select enum item.

Current behavior

It shows only textbox

2. run npm run gen-api-docs all or use following file batches-get-batches.api.mdx.txt
