Repro steps:

- Open SampleScene from the attached project
- Select the Point Light in the scene and drag its indirect multiplier
- Observe how only the point light changes in the scene, but the particle point light (which is using the same light) remains unchanged.
- Save and reload the level
- Observe how both lights are showing the correct bounce light.

(video with repro steps attached)

Note:
- indirect light for particles was just enabled in 18.3, so technically not a regression.
