Docker Compose configuration does not work with Repository configuration folders upon "Clone Repository... Named Volume"

[CezaryKlus]

I want to specify the Docker Compose-based spec for the devcontainer in a separate folder as here:

https://code.visualstudio.com/docs/devcontainers/create-dev-container#_alternative-repository-configuration-folders

However, docker-compose.yml (and any other file except the devcontainer.json) does not seem to be copied to the intermediate container (?) when I perform

stat /tmp/devcontainer-config-063e7fed-81a8-4bc3-beb2-0be1eee8514c/.devcontainer/docker-compose.yml: no such file or directory

The only file referenced from the "host" is --id-label devcontainer.config_file=...devcontainer.json

devcontainer.json is pretty standard:

	"name": ".NET 8 Multi-Container",
	"dockerComposeFile": "docker-compose.yml",
	"service": "dev",
	"workspaceFolder": "/workspace",
	"features": {
	},

So the Repository configuration is correctly picked up but the Docker compose in this scenario does not work.
