/**
 * Fixes the iteration of the `Headers` class with respect to `set-cookie` header:
 *
 * By default, multiple `set-cookie` headers will be concatenated by the `Headers` class implementation.
 * However, the HTTP protocol/browsers expect multiple `Set-Cookie` headers,
 * and do not recognize concatenated `Set-Cookie` headers.
 *
 * This helper function fixes this behavior, yielding multiple `set-cookie` key-value tuples,
 * provided that no cookie value contains the concatenation sequence `', '` (comma empty-space).
