The seaborn test also uses Matplotlib but was not wrapped in the cleanup fixture, As there are now 3 files that need this fixture, refactor to reduce code duplication.
The leftover figure from
test_seaborn
would cause a DeprecationWarning from Matplotlib 3.8 for closing the figures on the backend change (from thempl.use("template")
in the fixture), but this probably depends on if pytest chose to run it before the other tests or not.doc/source/whatsnew/vX.X.X.rst
