How to reproduce:
1. Open user-submitted project (TheVoidTest2018.zip)
2. Open "samplescene" scene
3. Ensure "bgStar" game object has "BGStars" shader assigned to it
4. Play the scene
5. Switch to scene view
6. Switch fog options for scene view
7. Zoom in and out of the scene

Expected result: Sprite renderer feeds time to the shader independently from the distance to the camera
Actual result: Sprite renderer stops feeding time to sprite shader once a certain distance from the camera is reached

Reproducible with: 2018.2.3f1, 2018.3.0a8
Could not test with: 2017.1, 2017.2, 2017.4, 2018.1 (Project compatibility issues)
