Metainfo (Appstream) data is not used (adopt-info, parse-info)

Bug Description

Given the following snapcraft.yaml:

name: rayforge
version: git
adopt-info: rayforge
confinement: strict
base: core24

apps:
  rayforge:
    extensions: [gnome]
    common-id: com.barebaric.rayforge
    desktop: share/applications/com.barebaric.rayforge.desktop

...

parts:
  rayforge:
    plugin: python
    source: .
    python-requirements:
      - requirements.txt
    build-packages:
      - python3-pip
      - python3-setuptools
      - git  # Required for git describe
    parse-info: [share/metainfo/com.barebaric.rayforge.metainfo.xml]

Full file: https://github.com/barebaric/rayforge/blob/main/snap/snapcraft.yaml

I am seeing that some attributes from the metadata appear to be adopted, while others are not.

What works: Summary and description.

What doesn't work: Website, license, screenshots, categories, ...

I am puzzled. Running snapcraft with --verbosity debug does not reveal anything containing "appstream" or "metainfo".

Here is the full metainfo:

      Rayforge is a desktop application for laser cutting and engraving.
      It provides an intuitive interface to create and manage laser
      cutting projects.
      Rayforge supports importing SVG, DXF, PDF, and PNGs, and provides
      advanced features such as multi step jobs, automatic path
      optimization, interpolation based on laser dot size, and much more.
