When using a Stationary or Movable Skylight with some reflection captures that are not using the High Quality Reflections (material setting) will have what appears to be an inverted mask for the reflection capture.

Tested with:
Broken - 4.14 Preview 1 Binary - CL-3167010
Broken - 4.15 Dev-Rendering - CL-3171167

Steps to Reproduce

1. Create a scene with A reflective material on a vertical wall and Geometry above for the ceiling.
2. Add a reflection capture here.
3. Add a skylight set to Stationary or Movable.
4. Build Lighting.

Results: The stationary skylight has an inverted mask for what should be blocked to allow the skylight in the reflection capture for the sky.

Expected: The Overhead geometry should block the skylight.
