Research direction

Start at the htmlTemplate() entry point and reproduce the failure using the template.html example in the issue. Trace how HTML template pieces are evaluated; done means interpolations inside HTML comments are ignored while active content such as {{content}} still renders without the missing id error.

Written by the indexing model from the issue text.

Description

Given the following template:

<!doctype html>

<html lang="en">
<head>
  <meta charset="utf-8">
</head>

<body>
  {{content}}
  <!-->
  <p id = "{{id}}>This used to be here</p>
  <-->
</body>
</html>

Running htmlTemplate("template.html", content = "xx") will fail:

> htmlTemplate("template.html", content = "xx")
Error in eval(parse(text = piece), env) : object 'id' not found

It would be nice if htmlTemplate() could ignore commented parts from the HTML file :)
