[Jobsets] PCB always renders with "floor" regardless of the checkbox in job settings

Description

Hello!

PCB render PNG jobs always render with the floor option enabled regardless of the checkbox in the job settings!

render_settings

Here is the result (there should be no shadows on the background)

Vacuum_LED_V1R0_PCB_bot

Here is what I see in the 3D viewer with the foor turned off:

Vacuum_LED_V1R0_manual

After render PCB job run the "Add floor" option becomes enabled in Preferences even for 3D viewer

raytracing_settings

Steps to reproduce

  1. Create a jobset file
  2. Create a PCB render job with settings mentioned above
  3. Create a destination and add the job to it
  4. Generate
