Description Ryosuke Niwa 2015-09-04 16:22:15 PDT
When creating an element with createElementNS, we should not preserve the cases.
e.g. document.createElementNS(HTMLNS, "html:table").tagName should be "HTML:TABLE" instead of "html:table".

See https://dom.spec.whatwg.org/#dom-document-createelementns

document.implementation.createDocument("http://www.w3.org/1999/xhtml", "div", null).createElementNS("http://www.w3.org/1999/xhtml", "i").tagName

fails but

document.createElementNS("http://www.w3.org/1999/xhtml", "i").tagName

successfully upper-cases the tag name so there's some XHTML document weirdness going on here.
