Windows

Describe the bug
The Game Studio Edit Screen textures turns black when the default Directional light intensity is set just below max value.

Even with the post effect Bright Filter off the shader has a hard time dealing with the high values.

To Reproduce
Steps to reproduce the behavior:

1. New Project
2. Set intensity of Direction light to 3.4028234663852886E+38

Expected behavior
The scene is bright white and not generating a black spots.

Additional context
I am trying to find the cause of multiple lighting bugs and stumble on this one that seemed unreported.
The image with Intensity 3.028234742258807E+38 maybe related to:
#2502
#325

Reproduce the issue in the Game Studio Edit Screen on Windows by setting Directional Light intensity to 3.4028234663852886E+38, with Bright Filter both enabled and disabled. Trace the directional-light shader and post-processing path from that entry point; done means the scene stays bright without black spots at the reported maximum value.
