pdoc3 references internal symbols instead of public ones

I am keeping my python implementation details in a package called _internal and export the methods, classes and variables that are supposed to be the public API by re-exporting them in the __init__.py of the parent package, e.g. like so:

from ._internal.interface import MyInterface
from ._internal.sample import MY_VAR, my_function

__all__ = ['MyInterface', 'MY_VAR', 'my_function']

the signature e.g. of my_function is:

def my_function(iface: MyInterface) -> str:
    """My function doc

    Args:
        iface: interface parameter doc

    Returns:
        return value doc
    """    

   ...

Expected Behavior

• all three entities from __all__ to be visible in the documentation
• the documentation of my_function to reference the public type MyInterface
• the documentation of the arguments of my_function to show type information
• ideally a link from the type MyInterface in the signature of my_function to the documentation of MyInterface

Actual Behavior

• the variable MY_VAR is not documented at all
• the signature of my_function shows the internal type name not the public one (it shows def my_function (iface: pdoc_test._internal.interface.MyInterface) ‑> str) instead of def my_function(iface: pdoc_test.MyInterface) ‑> str
• the documentation of the arguments and the return value of my_function does not show any type hint

Steps to Reproduce

I have create a small repo to reproduce at:
https://github.com/Carsten-Leue/pdoc-test

Generated documentation showing the issue is here:
https://carsten-leue.github.io/pdoc-test/pdoc_test/

Additional info

• pdoc version:
  0.8.3

Start with the linked pdoc-test repository and reproduce the output using the reported pdoc version and the package init.py re-exports shown here. Done means MY_VAR appears, signatures and argument or return documentation use the public names, and MyInterface can link to its generated documentation.
