eduroam works on systemd-networkd but not on NetworkManager

After two years and countless hours of trying to fix this issue, I was finally able to connect to eduroam (Enterprise WPA) from Arch. I was able to do this by ignoring NetworkManager entirely and using wpa_supplicant explicitly. Today I have learned of the existence of systemd-networkd and it allows me to connect to the internet. As I use NetworkManager on other machines for home WiFi connections, VPNs, etc., I would like to also get eduroam working with my original NetworkManager setup. Here is my current (working) setup:

> cat /etc/wpa_supplicant/wpa_supplicant-wlan0.conf`
network={
        ssid="eduroam"
        key_mgmt=WPA-EAP
        eap=PEAP
        identity="username@domain"
        password="********"
        phase2="auth=MSCHAPV2"
}

> systemctl stop NetworkManager.service 
> systemctl start wpa_supplicant@wlan0.service systemd-networkd.service systemd-resolved.service dhcpcd.service

I have the (to my eyes) equivalent NetworkManager config, which doesn't work:

> cat /etc/NetworkManager/system-connections/eduroam.nmconnection
[connection]

Hint: use 'journalctl -xe NM_CONNECTION=95580564-0352-438d-9804-364636618a28 + NM_DEVICE=wlan0' to get more details.
