This test plan item is about the notebook renderer API. Renderer present cell output and run a separate code file in the webview/iframe context (not the extension host). This is an exploratory test plan item and you should be writing a very simple alternative renderer for GH issue notebooks

1. install GH issue notebook (https://marketplace.visualstudio.com/items?itemName=ms-vscode.vscode-github-issue-notebooks)
2. create new extension
3. make yourself familiar with the notebookRenderer-contribution point and write an alternative renderer for the x-application/github-issues MIME type
4. ℹ️ use the @types/vscode-notebook-renderer for guidance and types definitions for renderer
