Repro steps:
1. Create a new default VFX
2. Remove any color blocks from it (i.e. the color over life in Output)
3. Add a Set Spawn Event Color block in the Spawn context
4. Make it Random and set it to use Per Component
5. In Initialize, add an inherit color block.

Result: new particles have a color ranging between white and black.
Expected outcome: rainbow-colored particles.

Note:
- recent regression from the infinite recompile bugfix
