#44773: Non Existing Child Page Redirects  Instead of 404

     Type:  defect (bug)   |     Status:  new
 Priority:  normal         |  Milestone:  Awaiting Review
Component:  Rewrite Rules  |    Version:  4.9.8
 Severity:  critical       |   Keywords:  needs-patch

 Steps to reproduce:

 1. Register Custom Post Type with hierarchical set to true (We'll call it
 events)
 2. Create the following structure in the CPT:
 * Test
 * Test 2
  * Child (Child of Test 2)
 3. Go to https://localhost/events/test/child and this will redirect you to
 https://localhost/events/test-2/child instead of returning a 404.

 Extra Step:
 If you create a normal page of "Test" and try to navigate to
 https://localhost/test/child, it will redirect to
 https://localhost/test-2/child.

 All this was done on vanilla WordPress on Twenty Seventeen theme.
