Jupyter Lab Not Loading Properly

Hi,

I've been experiencing an issue for some time now. While refreshing the browser can temporarily resolve it, I believe it's important to address this matter.

Initially, when I typed jupyter lab in the terminal, the jupyter interface would launch automatically. However, at some point, this functionality stopped. Now, every time I type jupyter lab, the command simply disappears and I have to refreshing the browser to see the command. I'm unsure if this change is intentional or if it's a bug that needs fixing.

Here is one example I have

devcontainer.json

{
	"name": "LP_Env",
	// Or use a Dockerfile or Docker Compose file. More info: https://containers.dev/guide/dockerfile
	"image": "mcr.microsoft.com/devcontainers/base:bullseye",
	
	// Use 'postCreateCommand' to run commands after the container is created.
	"postCreateCommand": "bash ./.devcontainer/postCreateCommand.sh",

	 // Configure tool-specific properties.
	 "customizations": {
        // Configure properties specific to VS Code.
        "vscode": {
            // Add the IDs of extensions you want installed when the container is created.
            "extensions": [
                "analytic-signal.preview-pdf"
            ]
        }
	}
}

postCreateCommand.sh

sudo apt update
sudo apt install python3 --yes
sudo ln -s /usr/bin/python3 /usr/local/bin/python
pip3 install jupyterlab

Any comments would be appreciated : )
