erratic result from colorscale validator test #5028
Description
The test tests/test_plotly_utils/validators/test_colorscale_validator.py::test_acceptance_named[Inferno_r] fails when the entire test suite is run with pytest tests in the codegen2 branch (PR #4978) but succeeds when pytest tests/test_plotly_utils/validators/test_colorscale_validator.py is run on its own. (Testing done with Python 3.11.9.)
