In CIS up to version 8.1 https blocking has been inconsistent, however this seems to have been fixed in CIS 8.2 BETA which will block https sites but not show you the block screen.

Perhaps off-topic but would it be technically possible for CIS to filter all applications instead of specific browsers?
