[HDRP] Lit Graph Master Node does not react to Ambient Occclusion input

Package: Shader Graph

-

How to reproduce:
1. Open the attached project named "Case_1261225" (Link in the notes below)
2. Open the "Daylight" Scene
3. Open the Skin shader graph and observe that Ambient Occlusion input is set
4. Try plugging and unplugging the G channel from Sample texture node to the AO input and observe the character's face for any changes

Expected result: Shader's material receives AO once the input is set and the graph is saved (Track_1261225_V2)
Actual result: Shader's material does not react to AO input changes (Track_1261225_V3)

Reproducible with: 2019.4.7f1(7.2.0, 7.3.1, 7.4.1), 2020.1.1f1(8.2.0), 2020.2.0a20(10.0.0-preview.27, 10.0.0-preview.30)

Notes:
1. Could not test below 7.2.0 due to graphs and materials breaking on downgrade
2. While this AO setup does not work HDRP Lit Graph it does work in the PBR graph which was used for the model's armor

  1. Resolution Note:

    This works as expected as there is no visible indirect ambient lighting in the scene and Ambient Occlusion only affects indirect lighting.
