Tested this again on a model consisting of just three database units (one cluster).
I again went through the procedure as documented. This led to all three units in a Blocked state, as before.
I then did:
juju run mysql-innodb-cluster/leader reboot-cluster-from-complete-outage
This brought the leader unit back to an Active state.
One of the remaining two units was then resumed:
juju run mysql-innodb-cluster/1 resume
This surprisingly brought the entire cluster online.
