Hi Ian, Did you try to reboot? Note that .link files are applied by udev (so usually during early boot). You can override their settings from .network files in some cases (at least with current git you can).
I was not able to reproduce here (with git). "journalctl -b -u systemd-udevd" may contain some hints if you can still reproduce when rebooting.
