Comment:
I haven't tried reproducing myself but the report is complete enough that
I trust the developer's judgment.
Anthony, can you confirm this is also an issue when running
`A.objects.prefetch_related('b__c__d'')`? What about
`B.objects.prefetch_related('c__d')`?
[https://docs.djangoproject.com/en/1.10/internals/contributing/triaging-
tickets/#bisecting-a-regression Bisecting the exact commit that introduced
the regression] would also be useful.
