How to debug it locally:

• Run any of the images in the local
  podman run -p 8888:8888 quay.io/opendatahub/workbench-images:jupyter-datascience-ubi9-python-3.9-2023a-20230814-a67cf5f start-singleuser.sh

• Clone the example repo into the jupyter notebook
  https://github.com/harshad16/data-science-pipeline-example

• Explore the pipeline properties and try to open the file browser
  and select the directory to see the issue.

• While inspecting the browser, the API is hitting:
  http://127.0.0.1:8888/api/contents/data-science-pipeline-example?content=1&1692112050453

• As the rendering on file structure is not happening,
  we need to check the logic here: https://github.com/elyra-ai/elyra/blob/3c27ada25a27b719529e88268bed38d135e40805/elyra/pipeline/properties.py#L1166

  to figure out what is missing in the browsing.

• Check jupyter file browser setting, and see if there is a significant difference:

In regards to the working on the issue,
this requires some knowledge of the jupyterlab Browser window file explorer.
Opening an issue upstream about this and will try to contribute there.
