Link tags appear at end of body

When displaying a form, the Gravity Forms stylesheets (e.g. formreset.css, formsmain.css, etc.) appear at the end of a page's body rather than in the document's head. Link elements are not supposed to exist outside the head, and this causes a W3C validation error. It also makes it slightly harder to override Gravity Forms styles in another stylesheet that's been enqueued and printed in the head. I've disabled CSS output and styled my forms manually, but is this a bug with Gravity Forms or Wordpress?

That's what I thought, too, which is why I got confused. I was originally building the form using do_shortcode() within a page template, outside the content loop. After I posted I realized that might be the problem so I replaced it with a form widget, which also causes the stylesheets to be printed in the footer

But the stylesheets are definitely getting to the header when the form is included in page content.
