str(zipfile.Path()) not working when root attribute is io.BytesIO

Using zipfile.Path with a ZIP-file "in memory" as io.BytesIO instance. In that case attributes like .filename() or .__str__() do not work because they try to instanciate a pathlib.Path() with a io.BytesIO object.

I can confirm this with Python 3.11 (run in Docker), Python 3.10.2 (Windows) and Python 3.9.2 (Debian stable). See output below for detailed version infos.

Code to reproduce

#!/usr/bin/env python3
import sys
import io
import pathlib
import zipfile

print('{} {}\n'.format(sys.platform, sys.version))

zip_bytes = io.BytesIO()

# create a zipfile in memory
with zipfile.ZipFile(zip_bytes, 'w') as zf:
    zf.writestr('entry.file', 'content')

# ZIP-Path object from in-memory-ZIP
my_zip_path = zipfile.Path(zip_bytes, 'entry.file')
print('Exists {}'.format(my_zip_path.exists()))

# here comes the Exception
print(my_zip_path)
