Oh wow, this is strange. And even more strange, I just found out a
very similar problem in my own host system running Arch, this time
with a net port instead of a cdc-wdm port:

ModemManager[461452]: <debug> [1592395909.393490] [base-manager]
adding port wwan0 at sysfs path:
/sys/devices/pci0000:00/0000:00:14.0/usb1/1-8/1-8.2/1-8.2:1.10/net/wwan0
ModemManager[461452]: <debug> [1592395909.394961] [base-manager] port
wwan0 not candidate
