If I use newest ver. 1.8.1 (when I use 1.7.0 work correct)

• I get problem with server.authenticate
• server.on(F("/"), {
  if (!server.authenticate(www_username, www_password))
  {
  return server.requestAuthentication();
  }
  server.send(200, F("text/plain"), F("Login OK"));
  });

If you call above you don't get LOGIN windows, but clear window and callin finis with :
return server.requestAuthentication();

• I testing on ESP32-S2 + W5500 + Ehtrenet3 lib (this lib I patchet library)
