SSGI AO not visible in Lit Viewmode

No screen space AO in lit viewmode with SSGI

Confirmed in 4.25 MAIN @ CL 10730208 (but you must move camera after activiating SSGI for scene to update)

1. Place some Cubes together to see Ambient Occlusion
2. While in lit mode and viewing AO enable SSGI

Result: AO can still be seen in AO Buffer Visualization, but not lit mode
