[BUG] docker compose watch fails to sync file changes for Node.js app when using bind mounts on Linux

[Vansh1811]

Description

Current behavior:
When running docker compose watch with a Node.js service on Linux, file changes in ./src are not synced to the container. The sync action does not detect host file modifications.

Expected behavior:
docker compose watch should detect file changes in watched paths and sync them to the container in real-time, enabling hot-reload without full restarts.

Steps To Reproduce

1. Create a Node.js project with a compose.yml using develop.watch with sync action
2. Run docker compose watch
3. Edit a .js file inside ./src on the host
4. Observe that the running container does NOT reflect the updated file
5. Restarting the service shows the file — confirming the sync is broken

please attach the watch section from your compose file for further analysis

Thanks for looking into this! Here's the develop.watch section from my compose.yml:

services:
  app:
    build: .
    volumes:
      - ./src:/app/src
    develop:
      watch:
        - action: sync
          path: ./src
          target: /app/src
          ignore:
            - node_modules/

Running Node.js with nodemon. File changes to ./src on the host are not triggering sync in the container. Restarting the service manually reflects changes fine, so the bind mount path is correct.

Environment: Ubuntu 22.04, Docker Engine 26.x, Compose v2.27.x
