The problem was that form_render() was being called from theme_weight as well
as from drupal_get_form(). Each call appended the prefix and appended the suffix,
so you were actually getting this:


I happened not to notice the extra suffix at first in the HTML output, but it
was there.

All that was needed was a pair of unset() calls added to theme_weight().

Under the "code is gold" premise, I've filed this as an issue (#38790) and have
contributed a patch to includes/form.inc.

I hope the forms API team find this helpful. Great piece of code, other than
this little glitch.
