Textarea renders with empty comment in SSR

[whastings]

When server-side rendering a template that uses the {{textarea}} helper, the textarea is rendered with an empty comment inside:

<textarea><!----></textarea> (tag attributes omitted for brevity)

This happens even when the value passed to the helper is a non-empty string (e.g. {{textarea value="foobar"}}).

Can we fix this so that the textarea will render with the contents of the helper's value instead of the empty comment in SSR?
