Using image map results in a release assertion inside DocumentOrderedMap::add while inserting an image element with usemap attribute.

e.g.

ASSERTION FAILED: &element.treeScope() == &treeScope
dom/DocumentOrderedMap.cpp(52) : void WebCore::DocumentOrderedMap::add(const WTF::AtomicStringImpl &, WebCore::Element &, const WebCore::TreeScope &)
