swagger-ui: Maximum call stack size exceeded of complicated schemas (FHIR for example)

On large schemas, Swagger UI either fails with RangeError: Maximum call stack size exceeded error or hangs with 100% CPU usage. In my case, these were the official FHIR schemas which may be downloaded by a link: https://www.hl7.org/fhir/fhir.schema.json.zip It would be enough to unzip them and copy the fhir.schema.json folder next to your swagger spec.

Demonstration API definition

{"swagger": "2.0",
 "schemes": ["http"],
 "info": {"contact": {"email": "test@test.com"},
          "title": "sdfsdfsf"},
 "paths": {"/foo": {"get": {"description": "sdfsdfsdfdsf",
                            "responses": {200: {"description": "sdfsdf",
                                                "schema": {"$ref": "./fhir.schema.json/Practitioner.schema.json"}}}
}}}}

Configuration (browser query string, constructor, config.yaml)

I didn’t change enything except the url parameter: url: "/swagger/schema",

Expected Behavior

To see the schemas.

Current Behavior

Either an exception (3.13.0) or an endless 100% CPU usage (3.13.2)

Context

I figured out by crafting a small subset of definitions out of these schemas.
