`leader-settings-changed` firing before unit departure

Hi team. I had some weird behavior for this set up / situation

For Example. If you have these units:

A *
B
C

and A departs then you get these events hooks for each unit: A: leader-settings-changed , mongodb-storage-detaching, mongodb-relation-departed(for A-B), mongodb-relation-departed(for A-C), stop, remove B: mongodb-relation-departed (for A-B) C: mongodb-relation-departed (for A-C),

According to @wallyworld and @rwcarlsen this is unexpected behaviour and should be looked into. As requested, this is my repo/branch where I observed this behaviour. It can be observed by first creating the necessary environment according to CONTRIBUTING.md. Once the environment has been created you can reproduce this with:

# pack and deploy
charmcraft pack
juju deploy -n3 ./*charm

# in a separate session
juju debug-hooks <leader_unit>

# remove unit 
juju remove-unit <leader_unit

This doesn’t feel like an operator framework issue, but a juju issue https://bugs.launchpad.net/juju/+filebug

If @wallyworld https://github.com/wallyworld could clarify exactly what juju should be doing here that would help inform the best approach for dealing with things in the ops framework here.
