After resuming from a suspend, the MBIM-managed Sierra Wireless EM7305 doesn't seem to properly allow connections if ModemManager had an open MBIM session during the suspension. After resuming, a connection attempt will make the device connected, but not working properly.

Would be good to get a set of ModemManager and NetworkManager debug logs of the same run.
