5.15: QtRemoteObject listener count keeps increasing at server side.

When running Qt\Examples\Qt-5.15.10 Remoteobjects\ssl When the clients (replicas) connect and disconnect to the host (source), the listeners count doesnt seem to come down on disconnect. They are only increasing all the time.

Attached example reproduces it. This seems working good with Qt6.7.2

Also attaching binary package.
Just run server and client wait for few seconds and then close client. 

Re Run client and wait for few seconds

you will see logs like:

qt.remoteobjects: # Listeners 7

above log I got after 7th time I started client and closed it.
