Thanks for finding this issue and discovering what's going on with message traces etc. To get it some visibility (and hopefully have Microsoft fix the problem), I wrote the problem up in https://office365itpros.com/2019/09/26/office-365-groups-ndr-oddity/ and have sent it to some folks in Microsoft who might be able to persuade some engineering effort to happen.
