Plotly reference guide 1.4.2rc1 issues

[MarcSkovMadsen]

When trying to run https://holoviz-dev.github.io/panel/reference/panes/Plotly.html via Pyodide I see the following issues

• [x] Errors in browser console
• [x] Streaming via add_periodic_callback example not working. The run button is now red. If I hover it says KeyError: 'id'
• [ ] Streaming via async generator. If I click the run button, I just see an empty plot. Nothings happening.
• [x] Event Inspection example: ModuleNotFoundError: No module named 'tornado'

Resolved some of the issues but still seeing issues with the generator. Also part of the issue is that all your examples call the resulting output plotly_pane so some of the callbacks end up referring to the wrong output.

Still something wrong with the async generator example, otherwise all seems to be working now.

There is also something wrong with that example when you "restart and run all". But it works when you manually run the cell.
