Add missing integration spec coverage.
Add missing integration spec coverage.

There are unit specs on the filter manager
that cover the filter manager’s involvement
in this behavior but nothing covered it as a whole,
and I’m working on a bug fix that may require
changes to the filter manager’s behavior, so
covering it with an integration spec ensures
we don’t regress.
