i2c_device reports no device, even though I2C.scan sees it

CircuitPython version

Adafruit CircuitPython 7.2.0-alpha.1-112-g9b32d549f-dirty on 2022-01-16; Adafruit Feather ESP32-S2 TFT with ESP32S2

Code/REPL

>>> i.try_lock(); i.scan(); i.unlock()
True
[11, 104]
>>> hex(104)
'0x68'
>>> import adafruit_pcf8523
>>> adafruit_pcf8523.PCF8523(board.I2C())

Behavior

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "adafruit_pcf8523.py", line 160, in __init__
  File "adafruit_bus_device/i2c_device.py", line 50, in __init__
  File "adafruit_bus_device/i2c_device.py", line 163, in __probe_for_device
ValueError: No I2C device at address: 0x68

Description

This only happens if the pure python adafruit_bus_device is used, the built in one works. (However, they should both work the same)

Additional information

Other weirdness: adafruit_bus_device is picked up from lib/ even though the built in version is available. Why? sys.path is ['', '/', '.frozen', '/lib']. Removing adafruit_bus_device from CIRCUITPY/lib (it was put there by circup) makes it work!
