Unable to change ESP32-S2 Power

WiFi.h for the ESP32 has many #include statements

#include "WiFiGeneric.h"

If you look in that file you will see this enum for wifi_power_t

typedef enum {
    WIFI_POWER_19_5dBm = 78,// 19.5dBm
    WIFI_POWER_19dBm = 76,// 19dBm
    WIFI_POWER_18_5dBm = 74,// 18.5dBm
    WIFI_POWER_17dBm = 68,// 17dBm
    WIFI_POWER_15dBm = 60,// 15dBm
    WIFI_POWER_13dBm = 52,// 13dBm
    WIFI_POWER_11dBm = 44,// 11dBm
    WIFI_POWER_8_5dBm = 34,// 8.5dBm
    WIFI_POWER_7dBm = 28,// 7dBm
    WIFI_POWER_5dBm = 20,// 5dBm
    WIFI_POWER_2dBm = 8,// 2dBm
    WIFI_POWER_MINUS_1dBm = -4// -1dBm
} wifi_power_t;

If you substitute one of the enum values in the .setTxPower( ) the code will compile without error.

#include <SPI.h>
#include <WiFi.h>

char ssid[] = "SSID1";
char pass[] = "PASS1";

void setup()
{
  Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  delay(100);
  WiFi.begin(ssid, pass);
  delay(5000);
}

void loop()
{
  delay(1000);
  if (WiFi.status() != WL_CONNECTED)
  {
    WiFi.disconnect();
    delay(1000);
    WiFi.begin(ssid, pass);
    delay(5000); // Allowing connection to be established, before reconnecting
  }
  else
  {
    //WiFi.setTxPower(70);
    WiFi.setTxPower(WIFI_POWER_18_5dBm);
    //WIFI_POWER_18_5dBm = 74
    int a = WiFi.getTxPower();
    Serial.print("TX power:");
    Serial.println(a);

    delay(2000);
  }
}

I am using the 2.0.0 alpha1 development release core through the board manager which includes the S2 and S3 in the master.
