Reproduction steps:
1. Open the attached “LightRenderingLayerMaskBug.zip“ project
2. Open the “Assets/Scenes/SampleScene.unity“ Scene
3. Enter the Play Mode
4. Observe the bounds of “Default Light“ and “LightLayer1 Light“ in the Console

Expected result: “Default Light” bounds are “Center: (0.00, 0.41, 0.00), Extents: (5.00, 0.50, 5.00)“, “LightLayer1 Light“ bounds are “Center: (-3.00, 1.00, 0.00), Extents: (0.50, 1.00, 0.50)”
Actual result: Both light bounds are “Center: (0.00, 0.96, 0.00), Extents: (5.00, 1.05, 5.00)“
