Notebook preload scripts load after the renderer scripts

[DonJayamanne]

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: Insider
• OS Version: N/A

Steps to Reproduce:

• Create a renderer with preload scripts using the new contribution notebookPreload
  • Add a console.log into this script
• Create an output with HTML in a notebook
  • Add a console.log into the output HTML
• Keep the notebook open and reload VS Code
• You'll notice that the output HTML script is executed first

I.e. the preloads are loaded after the renderer scripts.

Closing this as I can no longer repro this issue, possible i had an older version of insiders or the like.

I can still repro this issue, I think you should reload vscode with all editors closed, then open the notebook.
Seems to be a timing issue with activation of the extensions or the like.

@mjbvz this blocks microsoft/vscode-jupyter#6404 which was on the iteration plan, it kinda works. Kind of based on the timing of the loading of the pre-load scripts.
