Circumvent CORS restriction when testing

If the server you're using doesn't (yet) support CORS requests, then we got you covered. You may want to use the local CORS-ed tunneling server which you recognize with the /CORS/ subpath in the server URL. For each server you define in the Servers tab, we automatically add a CORS-ed one in the servers drop-down in the Web View. (The added CORS-ed servers will not be added to your OpenAPI document)
