Comment:
As mentioned on the pull request, this issue seems to exist for any of the
4 cases
[https://github.com/django/django/blob/master/django/db/models/sql/query.py#L400-L401
here]:
{{{
if (isinstance(self.group_by, list) or has_limit or
has_existing_annotations or
self.distinct):
}}}
I was able to write unit tests for all but the
{{{isinstance(self.group_by, list)}}} case, if someone is able to provide
a test for that case I can add it to my changes.
