I can confirm that this re-rendering does happen. Initially, it is a black screen, but resizing the browser window renders the graph properly. I initially thought it was blank because of the window size and did not think of the re-render scenario. It happens with almost every graph type in Plotly, too.

Further, I tried it in the non-databricks environment on Firefox, and it seemed to be working. If you are looking for a fix for Firefox without having to resize, I suggest reaching out to Databricks Support so that they can reach out to the Engineering team and check on getting a fix for this as this is reproducible in all DBR versions.

The current Workaround would be to resize the window once the workflow is run to see the visualisation.

Do let me know if you have any queries. If not, can we mark this as an accepted solution?
