Comment (by James Addison):
Adding this hack to the `Item` model addresses the issue for now. Yes, I
realize this is overriding an undocumented, internal Django `Model` method
and is thus fragile to future changes - but it's a hack that lets me
proceed for now and hopefully helps the Django team.
{{{
class Item(models.Model):
....
def _do_update(self, base_qs, *args, **kwargs):
qs = base_qs.all()
qs.query.annotations.clear()
return super()._do_update(qs, *args, **kwargs)
}}}
