Inherited class with overwritten method is not working as advertised in the doc

Expected Behavior

The doc says :

pdoc considers methods' docstrings inherited from superclass methods', following the normal class inheritance patterns. Consider the following code example:

>>> class A:
...     def test(self):
...         """Docstring for A."""
...         pass
...
>>> class B(A):
...     def test(self):
...         pass
...
>>> A.test.__doc__
'Docstring for A.'
>>> B.test.__doc__
None

In Python, the docstring for B.test doesn't exist, even though a docstring was defined for A.test. When pdoc generates documentation for the code such as above, it will automatically attach the docstring for A.test to B.test if B.test does not define its own docstring. In the default HTML template, such inherited docstrings are greyed out.

So I expect to see "test" in the methods of B, documented with the docstring of A.

Actual Behavior

In my tests with pdoc3 v0.5.0 to v0.6.2, I don't see "test" in the methods of B. It says it is inherited. It is in reality not the case as it is overwritten.

When I add a docstring to B.test, it reappears in the methods of B.

Steps to Reproduce

1. Create this file main.py :

class A:
    def test(self):
        """Docstring for A."""
        print("From A")


class B(A):
    def test(self):
        print("From B")

2. Run pdoc --html
3. Open the generated doc and remark that B.test is not listed in the method, as pdoc thinks it is inherited, which it is not.

Additional info

• pdoc version: 0.5.0, 0.6.0, 0.6.1, 0.6.2

Start with the main.py reproduction and run pdoc --html using the reported versions or the current package. Inspect how generated documentation decides whether B.test is inherited, then compare B's method listing with the expected inherited docstring behavior. Done means B.test appears in the generated methods with A.test's docstring when B.test has no docstring.
