Description Chris Dumez 2015-09-03 22:30:00 PDT 
Document.body should return the *first* body / frameset child of the html element as per the specification:
https://html.spec.whatwg.org/multipage/dom.html#the-body-element-2

Chrome and Firefox both behave correctly. However, WebKit first looks for a frameset child and returns it if it find one. It then falls back to looking for a body child. document.body thus returns a wrong result in this case:
<html>
  <body></body>
  <frameset></frameset>
</html>

This is covered by the following newly imported W3C test:
