Disconnect command is requesting wpa_supplicant both to disconnect from
the current AP (if any) and stop trying to connect any network.

In that case, there was no explicit request to stop connection attempts.

Yes

Requesting a new connection (e.g., reassociate, reattach, reconnect)
should enable scanning for a network.
