Authentication fails when using DIGEST_AUTH from iOS devices

[Hieromon]

Hardware:

Board: Heltec WiFi Kit 32
Core Installation version: 1.0.4
IDE name: Arduino IDE 1.8.10
Flash Frequency: 80MHz
PSRAM enabled: No
Upload Speed: 115200
Computer OS: iOS 13 on iPhone

Description:

HTTP authentication fails when using DIGEST_AUTH with WebServer::authenticate from iOS devices. It occurs in any of Safari, Firefox, and Chrome.
This could be an iOS13 issue, but the ESP8266 arduino core has dealt with a similar issue.
esp8266/Arduino#4717

How does the esp32 arduino-core will deal with this problem?

Sketch:

The below sketch as a quote from the HttpAdvancedAuth.ino.

#include <WiFi.h>
#include <ESPmDNS.h>
#include <ArduinoOTA.h>
#include <WebServer.h>

const char* ssid = "........";
const char* password = "........";

WebServer server(80);

const char* www_username = "admin";
const char* www_password = "esp32";
const char* www_realm = "Custom Auth Realm";
String authFailResponse = "Authentication Failed";

void setup() {
  Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  if (WiFi.waitForConnectResult() != WL_CONNECTED) {
    Serial.println("WiFi Connect Failed! Rebooting...");
    delay(1000);
    ESP.restart();
  }
  ArduinoOTA.begin();

  server.on("/", []() {
    if (!server.authenticate(www_username, www_password))
    {
      return server.requestAuthentication(DIGEST_AUTH, www_realm, authFailResponse);
    }
    server.send(200, "text/plain", "Login OK");
  });
  server.begin();

  Serial.print("Open http://");
  Serial.print(WiFi.localIP());
  Serial.println("/ in your browser to see it working");
}

void loop() {
  ArduinoOTA.handle();
  server.handleClient();
}
