Description

docker compose raises a permission denied error, if there is a folder in the watch path with insufficient permissions even if it is in the ignore list.

Steps To Reproduce

minimal docker-compose.yml:

services:
  app:
    image: alpine:latest
    command: ["sleep", "infinity"]

    volumes:
      - ./root-owned-dir:/data

    develop:
      watch:
        - action: sync
          path: ./
          target: /tmp
          ignore:
            - ./root-owned-dir/

Created root owned folder:

$ sudo mkdir -p root-owned-dir
$ sudo chmod 700 root-owned-dir

This works as expected:

$ docker compose up

But watch prints a permission denied error:

 $ docker compose up --watch    
[+] up 2/2
 ✔ Network watch-repro_default Created                                                                                                                                                                                                                   0.0s
 ✔ Container watch-repro-app-1 Created                                                                                                                                                                                                                   0.0s
notify.Add("/home/<SNIP>/watch-repro"): watcher.Add("/home/<SNIP>/watch-repro/root-owned-dir"): permission denied

root-owned-dir is in the ignore list, so I expect that it does not care about its permissions.
