Make UtilsTests.test_filter_params Python 3.13+ compatible Since Python 3.13.0a1, docstrings are automatically dedented. See https://github.com/python/cpython/issues/81283 and https://docs.python.org/3.13/whatsnew/3.13.html#other-language-changes
As a result, using a docstring with leading space as a test case breaks the test assumption.
The initial commit which introduced this test a decade ago (6c0c7914f3a57823834b1be492b307992f943629) does not specify why testing the spaces is important.
