System Information
Operating system: Windows-10-10.0.19042-SP0 64 Bits
Graphics card: NVIDIA GeForce GT 740/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 471.11

Blender Version
Broken: version: 3.0.0, branch: master, commit date: 2021-12-02 18:35, hash: f1cca30557
Worked: (newest version of Blender that worked as expected) I also tried nightly build

Short description of error
Image saved does not include all the layers

Exact steps for others to reproduce the error

I added a new layer and enabled a new collection for this with some objects
Went into composition and join these 2 layers via overlay. Backdrop shows the correct result but render layers node does not show a preview.
After render all good. If I save The second layer is missing.

Here is a blend file so that you test it. Hit the render and save the file after render. Compare the saved file with the render. You will see that the new layer is missing.
Blend file bug- image not saving with full composition
I tried everything I could think of, if this is not a bug... it is a big pain to figure it out.

Emission + Alpha + PNG don't work well together.
The alpha in the emission parts of the image is 0.0 so the PNG, on conversion, multiplies and makes the emission disappear.
This is the same issue reported in #81199 (Some effects [bloom, smoke, fire, ..] still don't save in PNG with transparent background (occlusion vs. emission)).
