Tested against the following scenario, where local builds (mysql-router-k8s and mysql-test-appare current latest/edge WITH this version of the library):

# Deploy
juju  deploy --trust  ./mysql-router-k8s_ubuntu-22.04-amd64.charm --resource mysql-router-image=ghcr.io/canonical/charmed-mysql@sha256:0f5fe7d7679b1881afde24ecfb9d14a9daade790ec787087aa5d8de1d7b00b21
juju deploy mysql-k8s --channel=8.0/edge
juju deploy --trust ./mysql-test-app_ubuntu-22.04-amd64_ubuntu-20.04-amd64.charm 

# Relate backend and router
juju relate mysql-k8s mysql-router-k8s

# Relate router test-app
juju relate mysql-test-app mysql-router-k8s

# Break backend-router relation
juju remove-relation mysql-router-k8s mysql-k8s

# Restore backnd-router relation
juju relate  mysql-router-k8s mysql-k8s

mysql-test-app continued function with no issues, everyone happy:
