tests/test_window.py(fix): Suppress secondary deprecation warning in test

why: The test `test_deprecated_window_methods_emit_warning[show_window_option_global]`
triggered two warnings: the expected one (Window method deprecated) and an unexpected
secondary one (g argument deprecated). The secondary warning leaked to pytest output.
what:
- Add @pytest.mark.filterwarnings to ignore "g argument is deprecated" warning
- Test still validates the primary deprecation warning via pytest.warns()
