--- Comment #3 from Andreu Botella <abotella at igalia.com> ---
For Set-Cookie, combining multiple values with comma followed by whitespace is lossy, since you can have valid values such as "foo=bar; Expires=Thu, 01 Jan 1970 00:00:00 GMT", or even "bar=baz; Path=/test/a, b=c" (where "/test/a, b=c" is the path). Therefore, you can't accurately split a pre-combined value. And this would be observable when constructing Headers instances.

Alternatively, since Set-Cookie is both a forbidden request and response header, `FetchHeaders` could keep track of the Set-Cookie values only if the guard is `FetchHeadersGuard::None`, while maybe storing the combined value in the underlying `HTTPHeaderMap`. This would work, but it seems fragile, since the `FetchHeaders` state would not directly correspond to the `HTTPHeaderMap`'s state.
