 *  Fix: Don't fail the call when the response code is ‘HTTP 102 Processing’ or
    ‘HTTP 103 Early Hints’.
 *  Fix: Read the response even if writing the request fails. This means you'll get a proper HTTP
    response even if the server rejects your request body.
 *  Fix: Use literal IP addresses directly rather than passing them to `DnsOverHttps`.
