Zigbee2mqtt reporting powered off device as online

I have some Linkind water sensors that I’m using around my house to detect leaks. The problem is that I took the batteries out of one of them to test an automation that would report it offline. But there is no change to it’s status after 2 days of sitting here powered off. ZigBee2mqtt still reports it as online, dry, and battery good. Any ideas how to get it to update?

It finally showed offline after two and a half days. Is there any way to make it report offline sooner? That seems like way to much time for a water leak sensor to even be usable.
