Issue raised by a user (#.poupi) on Discord.
When using an emission texture, the ambiant occlusion shows a hard edge where the texture pixels are fully black.

Steps to reproduce:

1. Decompress and import the attached "AO Emissive.zip" in a HDRP project.
2. Open the "AO Emissive.unity" scene.
3. Look at the dark side of the cube (opposite of sunlight).

Actual results:

Expected results: 

Smooth transition of the AO with the emission.

Reproducible with versions: 

6.3.0b5

Not reproducible with versions: 

Can’t test with versions: 

Tested on (OS): 

Windows

Notes:

• I didn't test for regression, it might be here since the beginning and never noticed ?
• Reducing the emission intensity to a very small value (but not 0) will look like the AO is very dim where the emission texture pixels are not fully black:
