Directional Lights impact Sprites they should not impact when the GameObjects are on different Rendering Layers

How to reproduce:
1. Open the “RenderLayerRepro.zip“ project
2. Open the “SampleScene”
3. Select the “Directional Light 2” under “Layer 2“ GameObject in the Hierarchy
4. Change the Intensity value between 0.5 and 1.5 in the Light Component in the Inspector
5. Observe the Scene view

Expected results: The “GO Layer 1“ GameObject lighting level remains the same, while the “GO Layer 2“ GameObject lighting level changes
Actual results: The “GO Layer 1“ GameObject lighting level switches with the “GO Layer 2“ GameObject whenever the light intensity value is higher than the intensity on the “Directional Light 1“
