SPIFFS.bdegin fails when TFT_eFEXH.h is included

Arduino IDE 1.8.19
ESP32 core 2.0.14 (library TFT_eFEXH does not compile with ESP32 core 3.x.y)
TFT_eFEXH version=0.0.8
TFT_eSPI version=2.5.43

Board ESP32 Dev Kit V1

Problem discovered with example Jpeg_ESP32 for library TFT_eFEXH (and also with example Rotate_Sprite_3 in the TFT_eSPI library.)
The SPIFFS has been loaded with the files in the data directory of sketch Jpeg_ESP32 and the content verified with a small test
derived from the standard SPIFFS_Test example, using only the listDir part.
Program always fails with an error on SPIFFS.begin()
From the Jpeg_ESP32 sketch, the following test has been extracted.
It seems that only the presence of #include <TFT_eFEX.h>, without any other use of the library is enough to show the error ....

void setup()
{
  Serial.begin(115200); // Used for messages and the C array generator
  delay(1000);
  Serial.println("\nESP32 SPIFFS.begin test ...");

  Serial.print ("+++++++++++ TFT_eFEXH");
#ifdef _TFT_eFEXH_
  Serial.println(" included  !!!!");
#else
  Serial.println(" not included !!!!");
#endif

  if (!SPIFFS.begin()) {
    Serial.println("SPIFFS initialisation failed!");
    while (1) yield(); // Stay here twiddling thumbs waiting
  }
  Serial.println("\r\nInitialisation done.");
}

void loop()

Here the results:
Run with #include <TFT_eFEX.h>

In fact the problem is in JPEGDecoder.h
TFT_eFEX.h make an include of JPEGDecoder.h
and JPEGDecoder.h is playing arround with include for FS.h, LittleFS.h, SD.h, SdFat.h etc ... and force the use of LittleFS instead of SPIFFS
For ESP32 and ESP8266

 #include <FS.h>
 #include <LittleFS.h>
 #define SPIFFS LittleFS

So the jpg files should be loaded from the data directory in LittleFS and not in SPIFFS as decribed in the comments of the examples.

In the comments of the example Rotate_Sprite_3 the link to the uploader is not convenient for LittleFS
Arduino ESP32 filesystem uploader is better

At least for ESP32 and ESP8266 the #include "SPIFFS.h" should be removed from the beginning of examples that used TFT_eFEX (Jpeg_ESP32, Rotate_Sprite_3 .... and other examples using SPIFFS and TFT_eFEX ...)
