Thanks for your contribution!

Could you please add some tests and a whats new entry:https://github.com/scikit-learn/scikit-learn/blob/main/doc/whats_new/upcoming_changes/README.md

Let's also specify in the docstring thateps is ignored if bothxlim andylim given. Could we also move the the new kwargs to underneatheps?

Please place your tests in the existing decision boundary test:sklearn/inspection/_plot/tests/test_boundary_decision_display.py.
You will be able to use the test data and fixtures, so you don't have to repeat.

Your test cases are probably too long and more than what is actually needed. If you are using LLMs to help you with tests, please note that they tend to produce verbose code and careful oversight and review by yourself is probably best.

Note also that we don't use test classes. I am happy to take another lookafter you've carefully reviewed your tests. Thank you
