Content Examples: Parallax Occlusion Map Feature no longer rendering self-shadows

Parallax Occlusion Map Feature fails to render self-shadows as of the release of Unreal Engine v4.24.0 and has not been remedied since. The feature is perfectly functional in v4.23 [See attachments to compare]

1. Download a fresh copy of the Content Examples project
2. Open Parallax Occlusion level.
3. Observe the self-shadowed example.
4. Create any material using the parallax occlusion self-shadowing feature.

 
Expected: Parallax Occlusion Map Feature should render self-shadows in Epic's own examples and with user-made materials.
 
Results: POM self-shadowing does not render.
