Latest version of Remote Containers causes an error when building my devcontainer

The latest version of remote containers no longer allows me to build a container that is externally defined in a dockerfile. The issue is fixed by going back to the previous version of the plugin.

• VSCode Version:1.72.0
• Local OS Version: Windows 11 21H2
• Remote OS Version: Ubuntu 20.04 (WSL2)
• Remote Extension/Connection Type: Container running in Docker desktop
• Logs: error.log

Steps to Reproduce:

1. Create new directory and drop the .devcontainer.json file in the root

{
  "name": "Tensorflow with Jupyter (GPU enabled)",
  "build": { "dockerfile": "docker/Dockerfile" },
  "forwardPorts": [8888],
  "postStartCommand": "nohup bash -c 'jupyter notebook --ip=0.0.0.0 --port=8888 --allow-root --NotebookApp.token=jupdevtoken &'",
  "runArgs": [
    "--gpus",
    "all"
  ],
  "extensions": [
    "ms-python.python",
    "ms-python.vscode-pylance",
    "ms-toolsai.jupyter"
  ]
}

2. Create a docker subdirectory, drop Dockerfile in that subdir

FROM tensorflow/tensorflow:latest-gpu-jupyter

RUN pip install pandas\
    sklearn\
    seaborn\

3. Start VS Code and restart the directory in the container
4. The following error occurs when building the container (full log in error.log

    error: failed to solve: rpc error: code = Unknown desc = failed to solve with fr
    ontend dockerfile.v0: failed to solve with frontend gateway.v0: rpc error: code    
    = Unknown desc = target stage dev_containers_target_stage could not be found
