 On the model

 {{{
 class Product(Model):
     properties = JSONField()
 }}}

 when querying with {{{Product.objects.values('properties__color')}}}, the
 resulting query is {{{SELECT ("product"."properties" -> 'color') FROM
 "product"}}}

 However, when using the equivalent F() expression {{{product =
 Product.objects.values(color=F('properties__color'))}} the resulting query
 is {{{SELECT "product"."properties" AS "color" FROM "product"}}}, which
 ignores part of the field name
