Description

System Information
Operating system: Windows
Graphics card: GeForce RTX 2080 Ti

Blender Version
Broken: 2.82

Short description of error
The Indirect Only setting on a Collection doesn't seem to apply when viewing Volume shaders through shaders with Transmission enabled.

Exact steps for others to reproduce the error
See the attached blendfile. Enabling or disabling the VOLUMETRICS collection (which is set to Indirect Only) doesn't affect what is seen through the glass.

Apparently it does work if the glass object is not inside the volume object. This defeats the purpose in many cases though.

Can confirm.

@Sergey Sharybin (sergey), @Brecht Van Lommel (brecht), @Stefan Werner (swerner): is this a known limitation?
