ESP32S3 touch low-power wake-up issue

[chengoxuan]

import machine
from machine import TouchPad, Pin
import esp32

t = TouchPad(Pin(4))#Other pins have also been selected
t.config(500) # ESP32S3 is slightly larger and set at 25000
esp32.wake_on_touch(True)
machine.lightsleep() # put the MCU to sleep until a touchpad is touched
###################################################################################################
The function of turning on touch to enter low-power and touch wake-up is normal on the ESPWROOM32 board, but it is not normal on ESP32S3

1. If ESP32S3 does not has PSRAM, the touch function can sometimes be normal and sometimes abnormal, and it cannot enter low power consumption
2. If ESP32S3 have PSRAM, the touch function is normal, but it cannot enter low power consumption
   How can I use the touch wake-up function of ESP32S3 normally?

I'm using a modified ESP32_GENERIC_S3 config for 16 MiB Flash and 8MiB SPIRAM_OCT compiled against ESP-IDF 5.1.
If I use esp32.wake_on_touch(True), then machine.lightsleep() does not work. It does not wakeup after given time in ms and the TouchPad does also nothing.

I thought I have used a GPIO which is not connected to RTC. But this was not the case. I tried GPIO1 and GPIO10.
