<style>
</style>

<script>
  // Ractive.load()
  // any comment
</script>

and parse the source file using rcu.parse() but got this error..

If i will remove the comment (// any comment) below // Ractive.load() comment, i wont get the error.

<p></p>

<style>
</style>

<script>
  // Ractive.load()
</script>

I tried different comments.. a full component with CSS JS and HTML and none of that matters as long as there's no comment below // Ractive.load()
