zsh-plugin not working in combination with non-root container-user

Feature id and version

ghcr.io/devcontainers-contrib/features/zsh-plugins:0.0.4

Devcontainer base Image

python:3.10

What happened?

If I set the containerUser and remoteUser to vscode the zsh-plugin stops working. The default shell is set to zsh and oh-my-zsh and the .zshrc seem to be set up correctly, however, with the wrong user rights (root, see output). A re-owning at the end of the install script should solve the matter.

For the sake of completeness I create the vscode user like so (extract from Dockerfile):

ARG USERNAME=vscode
ARG USER_UID=1001
ARG USER_GID=$USER_UID

# Create the user
RUN groupadd --gid $USER_GID $USERNAME \
    && useradd --uid $USER_UID --gid $USER_GID -m $USERNAME \
    # Add sudo support.
    && apt-get update \
    && apt-get install -y sudo \
    && echo $USERNAME ALL=\(root\) NOPASSWD:ALL > /etc/sudoers.d/$USERNAME \
    && chmod 0440 /etc/sudoers.d/$USERNAME

Also the location of the home dir is derived in a fragile manner in the install script (/home/$USERNAME) consider reading its location from the users $HOME.

EDIT: Adjusted command used to create vscode user.

Here is my work around: After adding the following to my devcontainers.json it works now:

"postCreateCommand": " sudo cp /root/.zshrc /home/vscode && sudo cp -r /root/.oh-my-zsh /home/vscode && sudo chown -R vscode:vscode /home/vscode"
