Docker image opens JupyterLab in tf directory despite declaring WORKDIR in Dockerfile

As stated in the title, I declare the WORKDIR in my Dockerfile as ‘/tf-project’, yet JupyterLab opens up with the directory ‘/tf’. It’s technically not a big deal since I can just remap the WORKDIR to that same folder and work from there. But, in case I ever have need to do otherwise, I want to understand why it’s doing this and how to “fix” it. Apparently JupyterLab opens a default directory based on a file named ’ `’. When I searched my WSL and Docker image file system, I could find no such file. But clearly the image is set up to go to this file dir. What am I missing?
