What is supposed happened?

When changing intensity of Directional Light, parts of scene should become brighter (which respond to light).

What happened?

Tried changing intensity from 1 to 10, 10 to 100. And there's no visual change.
Also tried toggling visible property of the entity, and still no change.

Steps to reproduce

- Set the render mode to `Shadows`
- Set a Directional Light component (if not set) and increase the intensity. 
- Toggle the `visible` property.
