Inline ignore not working correctly (also not with flake8)

[phistep]

pydocstyle is not obaying inline ignore comment flags # noqa: D for at least D403.

Versions:

$ python3 --version
Python 3.8.10
$ pydocstyle --version
6.1.1
$ flake8 --version
3.9.2 (flake8-docstrings: 1.6.0, pydocstyle: 6.1.1, mccabe: 0.6.1, pycodestyle: 2.7.0, pyflakes:
2.3.1) CPython 3.8.10 on Linux

Input:

"""MWE."""

def multiline():  # noqa: D401
    """Main entry point run on the clients and interacting with our cloud API.

    foo bar bar foo
    """
    ...

def oneline():  # noqa: D401
    """Main entry point run on the clients and interacting with our API."""
    ...

def ignore_all_D():  # noqa: D
    """Main entry point run on the clients and interacting with our API."""
    ...

def ignore_all():  # noqa
    """Main entry point run on the clients and interacting with our API."""
    ...

def other():  # noqa
    """lower case and no period"""

Expected result: no errors reported

Actual result:

$ pydocstyle doclint-ignore.py
doclint-ignore.py:15 in public function `ignore_all_D` (skipping D):
        D401: First line should be in imperative mood; try rephrasing (found 'Main')

Also there is a problem with flake8-docstrings which might be connected, I have reported it here: #54

flake8  --select D doclint-ignore.py

doclint-ignore.py:4:1: D401 First line should be in imperative mood; try rephrasing
doclint-ignore.py:11:1: D401 First line should be in imperative mood; try rephrasing
doclint-ignore.py:15:1: D401 First line should be in imperative mood; try rephrasing
doclint-ignore.py:19:1: D401 First line should be in imperative mood; try rephrasing
doclint-ignore.py:23:1: D400 First line should end with a period
doclint-ignore.py:23:1: D403 First word of the first line should be properly capitalized
