The current result is: "This should be a span: [object DOMHTMLElement]"
Also: javascript:alert(window.HTMLSpanElement) says "undefined". Looks like the reason is that there is no HTMLSpanElement interface in DOM 2 HTML. But this doesn't mean that we shouldn't be able to manipulate its constructor etc. See also: https://bugzilla.mozilla.org/show_bug.cgi?id=92071
@ap - is this something still we want to track or we can close this now? Thanks!
