What is the expected behavior when a scope is deactivated where there is a DHCP failover relationship

We have a site setup as follows:

DHCP Server 1

Scope 1 - Failover configured in load balance mode with 50/50 split

Scope 2 - Failover configured in load balance mode with 50/50 split

DHCP Server 2

Scope 1 - Failover configured in load balance mode with 50/50 split

Scope 2 - Failover configured in load balance mode with 50/50 split

All scopes have MCLT and state switchover of 30 minutes set.

We had an odd situation recently, where a customer accidentally deactivated Scope 2 on DHCP Server 2.

My question is, what is the expected behavior in this situation? Would DHCP Server 1 recognize that DHCP Server 2, Scope 2 was in a partner down state, even though the server itself was online, it was just Scope 2 that was deactivated? I've tried searching but can't find any documentation.

Looking at the event logs on DHCP Server 2, we can see event ID 74 in the DHCP logs showing that the scope had been deactivated but we can't see any logs on DHCP Server 1 to indicate it was aware the scope was deactivated.

Thanks
