Description

In Tests_Comment_GetDefaultCommentStatus (tests/phpunit/tests/comment/getDefaultCommentStatus.php), test_supported_custom_post_type_uses_opposed_comment_and_ping_options() registers a custom post type (with_comments_cpt) without unregistering it in tear_down().

This leaks the registered post type into the global registry, causing test pollution for subsequent test classes in the same run.

This PR adds a tear_down() method to Tests_Comment_GetDefaultCommentStatus to unregister with_comments_cpt.
