Broken: version: 2.83.0, branch: master, commit date: 2020-06-03 14:38, hash: rB211b6c29f771
Worked: (newest version of Blender that worked as expected)
Short description of error
[flame only does not render if 'transparent' is checked in 'film' under render settings]
Exact steps for others to reproduce the error
[Bake the attached and render with and without 'transparent' checked under 'film' in render settings. It works properly in the rendered viewport, but shows nothing in an F12 render.
This also happens in 2.9 Alpha June 24th build, and 2.82a release version (so I think it's been broken for a while).
Tried it on 3 different machines: get the same results on all of them.]
[Based on the default startup or an attached .blend file (as simple as possible)]
