Generated documentation leaves extraneous trailing whitespace on certain empty lines

[jonathandung]

When I use sphinx-autoapi to generate my API reference, doc8 complains that there are some instances of trailing whitespace. They are all of the following form:

.. py:class:: ClassName

   <Optionally bases + two blank lines>
   
   This is the docstring of the `__init__` method of the class. The above line in the source is not empty; it contains three spaces.

Relevant snippet of my conf.py:

extensions = ['sphinx.ext.napoleon', 'sphinx.ext.viewcode', 'autoapi.extension']
autoapi_file_patterns = ['*.pyi']
autoapi_python_class_content = 'both'
autoapi_member_order = 'groupwise'
autoapi_options = ['members', 'undoc-members', 'show-inheritance', 'show-module-summary', 'special-members']
