Same problem here. But I guess nothing is happening here?

Well - I was able to get the preview to sort of work by hacking the showPreview.js file in the extension to remove the template reference. (But the default template uses a popup overlay which does not seem to work inside of VS Code. So, it seems the template they have is the problem and needs to be updated.

With VS Code 1.33.0 vscode.previewHtml is deprecated.

Here is a commit of another extension which removed it from their code, and how they replaced it.

I'm also encountering this issue. This problem seems a pretty fundamental issue as I'd imagine the securedBy attribute is an important and core feature of documenting any API specification.
