Disconnected Flap -> Connect status does not change

[ChristophCaina]

For debugging severe issues with my zigbee network after implementing / pairing the Sure Petcare flap with the hub, I disconnected the hub from the power - and removed the batteries from the flap.

The connection status for the Hub will be shown correctly in SureHA:

But the flap itself does not update the connection status, and is still shown as connected:

I would expect the flap to switch to disconnected, when the hub is offline - since the flap can't connect to the cloud then (especially, without its batteries ;) )
