[whatwg/fetch] fetch with request mode as no-cors is causing strict cross origin resource accessable (#994)

i am using spring boot with cross origin configured for path "/getData" at "http://localhost:8080" as below
```
registry.addMapping("/getData")
     .allowedOrigins("http://localhost:4000")
           .allowedHeaders("POST, GET, OPTIONS, DELETE");
```

if i try `fetch("http://localhost:8080/getData",{mode:'no-cors'}) ` from "http://localhost:9090".
i am able to access resources. is it intended behaviour or some issue?
