Contributor guide
Research direction
No files or tests are named. Start by reproducing the blocked plot display in JupyterLab 3.3.1 with the listed Dask and dask-labextension versions, then inspect the HTTP request reported by the error. Done means plots display in the stated JupyterHub and Ubuntu container environment without the HTTP-blocking error.
