<pre>Maybe you were referring to the following check in the test?
===
test(function() {
var parent = node.cloneNode();
assert_throws('HierarchyRequestError', function() { parent.prepend('text'); });
assert_array_equals(parent.childNodes, []);
}, 'Document.prepend() with text as an argument, on a Document having no child.');
===
If so, the reason this is expected to throw is because the parent is a Document and the child is a Text Node (step 5 of <a href="https://dom.spec.whatwg.org/#concept-node-ensure-pre-insertion-validity">https://dom.spec.whatwg.org/#concept-node-ensure-pre-insertion-validity</a>).</pre>
