Comment (by Matthias Kestenholz):

 I added another commit on top
 
(https://github.com/django/django/pull/12394/commits/42fb622f8895f59ff6ad76b761c1eb9b41fd9549)
 which tests the `RESTRICT` case.

 The `RESTRICT` case shows a foreign key which actually exists, but it does
 not point at the `P` object yet but at the intermediate `R` object. It
 does not crash because there is no code accessing the first restricted
 object as is the case with protected objects.
