if uart receives 0xf0 byte then mcu after entering lightsleep never wakes up

Checks

• I agree to follow the MicroPython Code of Conduct to ensure a safe and respectful space for everyone.

• I've searched for existing issues matching this bug, and didn't find any.

Port, board and/or hardware

RP2, STM32L4, STM32H7

MicroPython version

MicroPython v1.22.2 on 2024-02-22; Raspberry Pi Pico with RP2040

Reproduction

Example for Rpi Pico:

from machine import Pin, UART, lightsleep
from time import sleep

uart = UART(0, baudrate=115200, bits=8, tx=Pin(0), rx=Pin(1), parity=None, stop = 1, timeout=2000)

## Main Loop ##
uart.write("Start \n")

while True:
    sleep(1)
    buff=bytearray()
    while uart.any():
        buff.extend(bytearray(uart.read(uart.any())))
    # to exit program send '9'
    if buff.find(b"9")>=0:
        break 
    
    if len(buff)>0:
        buff.append(10)
        uart.write(buff)
    uart.write("before lightsleep \n")
    lightsleep(100)
    sleep(0.05)
    uart.write("after lightsleep\n")

Expected behaviour

No response

Observed behaviour

If uart receives 0xf0 byte then mcu after entering lightsleep never wakes up.
If message doesn't have 0xf0 byte then it continues working ok.

I tried it on RPi Pico, and STM32 boards they have same behavior.

Additional Information

No, I've provided everything above.

Reproduce the issue with machine.UART and lightsleep using the provided Raspberry Pi Pico example, then compare behavior on the listed RP2, STM32L4, and STM32H7 ports. Trace the UART receive and lightsleep entry points; done means the MCU wakes and continues after receiving 0xf0, while existing behavior remains intact for other bytes.
