I’m sorry it doesn’t seem to be working, but with so many requests that we get here and in the VS Code issue tracker, we just cannot provide the support we would like to offer.

That said, if you can track down your issue to a specific problem of the Monaco editor, we are more than welcoming a PR by the community!

I’ll close this issue, but if you have specific follow up questions, we’ll try to help as good as we can given the limited resources that we have.

Thanks for your understanding!
