Well damn. I was under the impression that the communication channel uses/accepts only well defined VSCode specific messages related to the UI...

Darn. Maybe the solution is to use vs-code client in the browser? Like vscode.dev or https://github.com/coder/code-server ? It limits what keyboard shortcuts and extensions are available, but at least it's in a secure sandbox on the client side.
