A point light's source length appears to be 0 if too many are on screen at once

If a user places too many point lights on screen at once with a source length greater than 0 it will appear as though the length is 0

1. Download attached project
2. Open project
3. Play in Editor
4. Try to get as many lights on screen at once as possible
