Niagara Preview viewport is unaffected by Preview Scene Setting Environment Color

Preview Scene Setting Environment Color only shows as black in Niagara editor viewports

This issue does not reproduce in the Material, Static Mesh, Skeletal Mesh, Anim BP, or Control Rig Editors.

1. Open a project
2. Create and open a new Niagara Emitter or System
3. From the File menu bar, select Window > Preview Scene Settings
4. In the Preview Scene Settings window, expand Environment
5. Disable Show Environment
6. Set Environment Color to any color other than black

Result: The Preview viewport's Environment Color stays black

Expected Result: The Preview viewport's Environment Color should match what is set in Preview Scene Settings
