Widget Component Ignores Bounds Scale

When a widget component is using it's own bounds scale the value doesn't appear to have an effect in the editor. To verify this I added a parent component and used it's bounds scale with the same value and got different results.

1. Open attached Project
2. PIE and move the camera so that the plane on the left is blocked by the wall

RESULT
Plane on the left gets culled when occluded by the wall

EXPECTED
Plane continues to render after being occluded by the wall

NOTE
Plane on right doesn't get occluded because it is using the parent component to calculate bounds scale

3D Widget With Depth Pass Disabled Still Being Occluded
