(I guess you mean systemd-networkd instead of systems-resolved)
The way it should work is that if you lose the carrier on a link and
then regain it we should renew the lease. If your machine is directly
connected to the router and the router is rebooted, this should be
triggered. So this sounds like a bug to me.

Not known, so may I ask you to start networkd from the command line as
follows and send the output:
# SYSTEMD_LOG_LEVEL=debug /lib/systemd/systemd-networkd
In particular, point out at what point in the logs you restart the router.
Thanks for the report.
