Since the new-in-3.8 admin styling is more liberal in allowing IE7 and IE8 to gracefully degrade, we really are overdue to make the jump. This should fix issues with and future-proof list tables that are altered via AJAX, such as comments (#25060). Going to leave the classes in CSS for back-compat.
