Require (only) one specific job in matrix to finish for other dependent job

In GitHub Actions, imagine I have a build configuration like this, which builds my program on 3 different OSes and tests it on Ubuntu:

name: build-and-test

jobs:
  build:
    runs-on: ${{ matrix.os }}
    strategy:
      fail-fast: false
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]


  test:
    runs-on: ubuntu-latest
    needs: build

I would like the test job to depend on the Ubuntu run from the build job. However, now it depends on all three. How can I specify that the test job only needs the ubuntu run from the build job to finish before it starts running, and not all three?

TL;DR: I would like the test job to run as soon as the Ubuntu build job is finished, and not wait on the macOS and Windows ones.

This is not possible based on the current implementation of GitHub Actions. My suggestion would be to pull out ubuntu into its own job, this way its execution is independent of the others.

name: build-and-test

jobs:
  build-slow:
    runs-on: ${{ matrix.os }}
    strategy:
      fail-fast: false
      matrix:
        os: [macos-latest, windows-latest]

  build-ubuntu:
    runs-on: ubuntu-latest
    strategy:
      fail-fast: false
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]

  test:
    runs-on: ubuntu-latest
    needs: build-ubuntu
