"Download file" for HTTP code 400 do not download the file correctly

• OS: Windows 10
• Browser: Firefox (also same in latest Chrome)
• Version: 98
• Method of installation: NuGet
• Swagger-UI version: 4.5.0
• Swagger/OpenAPI version: Swagger 2.0, OpenAPI 3.0.1

When I return a file with a code 200 I'm presented with "Download file" which will download the provided file, but if I change the return code to 400 I will still get the "Download file" option but it wont use the file provided in the response body. Instead I will get a file which only contains the text "OrderedMap {}". I can observe in the network traffic that the correct file is sent, and that no other parameters in the response have changed except for the status code.

Steps to reproduce the behavior:

1. Make a request to an endpoint which returns a file with a status 400 code, in my case producing:

HTTP/1.1 400 Bad Request
Content-Length: 3877
Content-Type: application/octet-stream
Date: Mon, 28 Mar 2022 13:44:54 GMT
Server: Kestrel
Content-Disposition: attachment; filename=string.xlsx; filename*=UTF-8''string.xlsx

2. Click "Download file".

Expected behavior

The file which was sent in the request body is downloaded.

Additional context or thoughts

I'd guess there currently exist some logic which either special handle 200 OK response to give correct file or 400 Bad request to be a specific format?

Start by reproducing the Swagger UI "Download file" behavior with a 400 response carrying the shown application/octet-stream headers, and compare it with the 200 response in the network traffic. Trace the response handling that produces the download and verify that the downloaded content matches the response body rather than "OrderedMap {}".
