Cython modules that use __init__.pyx instead of __init__.py are broken with sphinxcontrib.apidoc

[ghost]

Describe the bug
Cython modules that use __init__.pyx/__init__.so instead of __init__.py are broken with sphinxcontrib.apidoc. They appear to be not picked up correctly by whatever internal component that uses (apidoc or autodoc I assume) and it gives a strange listing of the parent folder of the module only

To Reproduce
Steps to reproduce the behavior:

$ git clone https://github.com/wobblui/wobblui ./testblah
$ cd testblah/docs
$ make html
$ # open ./build/html/reference/modules.html and see it lists the "src" folder instead of the "wobblui" module

Expected behavior
docs/build/html/reference/modules.html will list "wobblui" module after docs build (that DOES happen by the way if you touch src/wobblui/__init__.py, but of course that breaks the module and the functions in src/wobblui/__init__.pyx may not be documented properly)

Your project
https://github.com/wobblui/wobblui (docs are inside "docs" folder, try "make html" as in steps above)

Screenshots

Environment info

• OS: Linux
• Python version: 3.7.3
• Sphinx version: sphinx-quickstart --version says 1.7.6
• Sphinx extensions: sphinxcontrib.apidoc should be the relevant one
• Extra tools: none that I'm aware of(?)

Additional context
I already filed a ticket here: sphinx-contrib/apidoc#13 and it was suggested that the problem is probably in sphinx itself or apidoc/autodoc

Is anyone aware of a workaround? Other than just adding an __init__.py file which doesn't fully do the job since then the __init__.pyx won't get documented (but at least the other modules will I suppose). I would also be interested in trying out any dev version of sphinx with an experimental change to improve this

Unfortunately, current implementation of apidoc only refers __init__.py. So we need to modify apidoc to do that. But I'm not familiar with apidoc. So it is a bit tough work to me...
