No refraction effect on the glass material in Unified Lighting

Enabling the beta function “Unified Lighting” breaks the refraction effect on the glass material at the LightingStyle=Soft setting, which did not happen in Voxel lighting technology.

with Unified:

without Unified:

Reproduction:
1. enable Unified Lighting in Studio beta features;
2. set LightingStyle to Soft and disable PrioritizeLightingQuality.

System:
* Windows 11
* CPU: AMD Ryzen 5 5500U 2.10 GHz
* GPU: Integrated
* Memory: 8 GB
* Studio Settings > Rendering > Graphics mode: Direct3D11

Expected behavior

The glass refraction effect should still work as before to match the visual style before the update.
