This looks like an issue very similar to #28621, only in this case the
issue is cause by using the annotation on the LHS of a filter.
For example,
{{{
class A(models.Model):
r = IntegerRangeField()
A.objects.annotate(x=OuterRef("x")).filter(x__contained_in=F("r"))
}}}
will result in the following stack trace:
{{{
