Filter provided via configUrl does not work

Q&A (please complete the following information)

• OS: Windows 10
• Browser: Microsoft Edge
• Version: 96.0.1054.43
• Method of installation: webjars/swagger-ui
• Swagger-UI version: 4.1.3
• Swagger/OpenAPI version: OpenAPI 3.0

Swagger-UI configuration options:

// Begin Swagger UI call region
const ui = SwaggerUIBundle({
  configUrl: "swagger-resources/configuration/ui",
  dom_id: '#swagger-ui',
  deepLinking: true,
  presets: [
    SwaggerUIBundle.presets.apis,
    SwaggerUIStandalonePreset
  ],
  plugins: [
    SwaggerUIBundle.plugins.DownloadUrl
  ],
  layout: "StandaloneLayout"
});
// End Swagger UI call region

Describe the bug you're encountering

Swagger-UI is able to load configuration from configUrl just fine, but seems to ignore the filter provided there. Below is an example of what is returned from my configUrl:

{
   "url":"/documentation/swagger.json",
   "deepLinking":true,
   "displayOperationId":false,
   "defaultModelsExpandDepth":-1,
   "defaultModelExpandDepth":10,
   "defaultModelRendering":"example",
   "displayRequestDuration":false,
   "docExpansion":"none",
   "filter":"test",
   "operationsSorter":"alpha",
   "showExtensions":false,
   "showCommonExtensions":false,
   "tagsSorter":"alpha",
   "tryItOutEnabled":true,
   "supportedSubmitMethods":[
      "get",
      "put",
      "post",
      "delete",
      "options",
      "head",
      "patch",
      "trace"
   ],
   "validatorUrl":"none",
   "withCredentials":false
}

To reproduce...

Steps to reproduce the behavior:

1. provide configUrl
2. let configUrl return a filter
3. look for the filter to be applied or the filter "edit box" to appear
4. it does not

Expected behavior

If I provide a filter directly in the Swagger-UI configuration (i.e. not via a configUrl) it works as expected.

No source file or test is named in the issue. Start by tracing how configUrl responses are loaded and merged with the Swagger UI configuration, then follow the filter option to the filter control. Done means a filter returned by configUrl is applied and the filter edit box appears, matching the behavior of a directly supplied filter.
