Comment 6 for bug 1870013

PR https://github.com/juju/juju/pull/11790 includes a stop gap fix for 2.8 that filters 'relation-ids' output to remove dead relations.

Note that this fix does not address the underlying issue (correctly populating the hook context for network-get) but rather ensures that workflows that iterate the output of relation-ids and then query juju for additional relation information (the scenario described in the bug report) will not observe dead relations.

We should probably open another bug specifically for fixing the hook context issue in network-get.
