Comment (by Martin Svoboda):
Thank you, your recommendation actually fix the problem. I propose the
patch https://github.com/django/django/pull/14762
I found one problem with the solution. prefetch_related sets
tag.content_object to None, but access to this tag.content_object actually
cause extra lookup query.
