Docker Compose build secrets are not injected in the Dockerfile

Question

Docker Compose has support for build time secrets since a while now. I tried using Docker Compose build secrets using the samples provided in the Docker Compose pull request but the secrets are not injected in the Dockerfile when I use docker compose build. I'm using Docker Desktop on Windows 10 (I just did a fresh install). When trying the same command using the same files in an Ubuntu VM, the secrets are injected in the Dockerfile.

What could be wrong?

docker-compose.yml

services:
  ssh:
    image: build-test-secret
    build:
      context: .
      secrets:
        - mysecret

secrets:
  mysecret:
    file: ./secret.txt

Dockerfile

FROM alpine

RUN echo "foo" > /tmp/expected
RUN --mount=type=secret,id=mysecret cat /run/secrets/mysecret > /tmp/actual
RUN diff /tmp/expected /tmp/actual

secret.txt

foo

The output of docker version on the Windows 10 machine is:
