This patch changes assumption to check a block to apply style as |HTMLElement|
to |Element| in |ApplyStyleCommand::applyBlockStyle()| to work with
non-HTML
element, a namespaceURI of element is other than HTML namespace URI.

Note: We can create and insert non-HTML element by document.createElementNS().
