deepObject query parameter does not work

[siddhsql]

Q&A (please complete the following information)

• OS: Windows
• Browser: chrome
• Version: 131.0
• Method of installation: [e.g. npm, dist assets]
• Swagger-UI version: not sure. I am using

<dependency>
      <groupId>org.springdoc</groupId>
      <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
      <version>2.5.0</version>
      <scope>runtime</scope>
   </dependency>   

which seems to be using Swagger UI version 5.13.0. see this

• Swagger/OpenAPI version: [e.g. Swagger 2.0, OpenAPI 3.0] openapi: 3.0.1

Content & configuration

Example Swagger/OpenAPI definition:

parameters:        
        - name: metadata
          in: query
          required: false
          style: deepObject
          explode: true
          schema:
            type: object
            additionalProperties:
              type: string        

full config is omitted to show just the part in question

Describe the bug you're encountering

I do not see any field for metadata in the UI

To reproduce...

• declare a query parameter of type deepObject
• open Swagger UI

Expected behavior

I should be seeing a field to enter metadata information
