matplotlib tests fail, expecting their decorator to be outermost

In the 3.5 version of this project: https://github.com/matplotlib/matplotlib

Revision de98877e3dc45de8dd441d008f23d88738dc015d

Create venv
pip install -r requirements/dev/dev-requirements.txt
pip install -r requirements/testing/all.txt
pip install pytest-xdist pytest appmap
pytest -vv

(most tests will pass)

run appmap-python pytest -vv - all tests will fail.

They all fail with the same error. Here is a single test example.

appmap-python pytest -vv で失敗を再現し、続いて _appmap/importer.py と _appmap/instrument.py のインストルメンテーションパスを、示されている Matplotlib の箇所である lib/matplotlib/pyplot.py、lib/matplotlib/testing/decorators.py、lib/matplotlib/_api/deprecation.py と併せて調査します。再現した Matplotlib のテストが、デコレータの順序またはラップされたシグネチャが無効であることを理由に失敗しなくなれば完了です。
