Description (partial)

It is confirmed the use of the dhcp-network-scope under a group policy in a context add ip address to the persistent list. 

Then, when we make the interface up in another context, first it will add the deny rule for the interface ip address and then it will check the persistent list, if there is any ip address in that list, it will add the deny rule for that ip address also irrespective of the context.

This is causing traffic destined to the dhcp-network-scope IP address getting blocked in specific ASA contexts.
