Depth of Field Blur on Cinematic Camera Not Working Before Focal Point

The depth of field blur when viewing through a cinematic camera no longer blurs between the camera and the point of focus. This is a regression; it was working as intended in 4.17.

1. Create new scene in 4.17 with starter content (with 2 chairs and table)
2. Place cinematic camera close to object like in attached image "workingblur417"
3. Observe Depth of Field blur between the focal point and the camera is blurred as intended.
4. Now open the sample project in 4.18 and view through CineCameraActor
   Result: Blur is not working between focal point and camera as shown in attached image "DoF_4.18"
   Expected: Blur should function same as in 4.17
