ID 552909 - Self-illuminated items become double-sided when the Camera Clipping Plane option is enabled.

 
Steps to reproduce
 
1) Download and open the attached scene file.

2) Render the scene file to see how it currently looks with the single-sided illuminated polygon at the top.

3) Select the Camera item, go to the Camera Effects tab, and enable the Clipping Plane option.
 
4) Render the scene file again and see that the illuminated polygon has become double-sided.

 
Expected behaviour
The polygon should remain the same regardless of the Clipping Plane option.
 
Actual behaviour
The polygon illuminates from both sides when the Clipping Plane option is enabled.
 
Workaround
Selecting the Material item and enabling Matte Clipping on the material item produces a result that isn't exactly the same but very similar to how it looks without having the Clipping Plane option enabled.
