Initial iframe tag: <iframe id="iframe" src="about:blank" scrolling="auto" contenteditable="true"></iframe>
Component: Untriaged → API: DOM

Workround - Insert the following before the createHTMLDocument.
iframe.contentDocument.open();
iframe.contentDocument.write("<!DOCTYPE html>\n");
iframe.contentDocument.close();
iframe is the existing iframe element.

This appears to actually be a Firefox bug. According to the specification, step 3 when handling createHTMLDocument() is "Append a new doctype, with 'html' as its name and with its node document set to [the new document]".
Reassigning for the dev team to evaluate.

http://software.hixie.ch/utilities/js/live-dom-viewer/saved/4946 shows we correctly create a document with a doctype. The live example shows that if you create a document with a doctype, and then transfer only the root element (and not the doctype!) to another document (that never had a doctype), the other document doesn't magically gain a doctype.
