[issue38878] os.PathLike subclasshook causes subclass checks true on abstract implementation

[Brett Cannon]

Brett Cannon <brett at python.org> added the comment:

I can't reproduce in Python 3.8.0:

>>> import os
>>> class A(os.PathLike): pass
...
>>> class B:
...     def __fspath__(self): pass
...
>>> issubclass(B, A)
True

Did you check against an older version of Python?
