astro docs edit in web publisher doesn't run

[o-az]

Describe the bug

following the Web Publisher docs here: https://developer.stackblitz.com/codeflow/content-updates-with-web-publisher#edit-this-page-on-github-link

I clicked on the edit page at the bottom of this page: https://docs.astro.build/en/basics/layouts/

then I replaced github.com with pr.new which launched a Web Publisher markdown editing page. However, I couldn't get it to run as it ket failing right away and the error are half blocked by the layout:
