I can also confirm this. One has to configure it manually in Wicked Service and
then go back to networkmanager for the devices to appear in the firewall.
If I recall correctly in desktops the wicked service is used by default (at
least it was the case for ifup) so that won't be a problem. But for laptops the
default is network manager so users will be unprotected. 
The firewall is turned on by default so I never crossed my mind to look it up,
until I wanted the change the firewall zone for a particular network device.
