Discussed in the triage meeting - moving to V3 as a coverage closure task.

Worth @GregAC looking into this and seeing if this is still an issue or not. If no longer relevant can close out, otherwise should check priority and milestone. @moidx

As this is a V3 issue, I'm moving this to the M7 milestone.
