 {{{
 #!CommitTicketReference repository="" revision="28613"
 If `post__in` or `post_parent__in` is passed to `WP_Query` as an empty
 array, nuke the query. Both vars are currently only checked for truthiness
 after which they are ignored. Setting these vars at all indicates explicit
 filtering being desired.

 Adds unit test.

 Fixes #28099.
