BUG: CkRest cannot decode gzip response

CkRest rest;
CkString output;

rest.Connect("www.google.com", 443, true, false);
rest.AddHeader("Accept-Encoding", "gzip");
rest.SendReqNoBody("GET", "/about/")
rest.get_ResponseHeader(output);
rest.ReadRespBodyString(output); // <------ this fails

CkRest works if I try to use deflate instead of gzip.

Same thing works with no issues for CkHttp:

CkHttp http;
CkString output;

http.put_AllowGzip(true);
http.QuickGetStr("https://www.google.com/about/", output)
