--rcs (reuse class session) has the same effect as --rs for sb pytest fixture tests

--rcs (reuse class session) is keeping the browser session open between tests of different classes when using the sb pytest fixture. That mode should only be reusing the browser session between tests of the same class.

(--rcs is working normally for tests that inherit BaseCase. This issue is specific to the sb pytest fixture.)

This behavior is expected to be different from pytest --rs, where all tests (regardless of class) should be reusing the same browser session.
