We don't need to check isHTMLElement, and don't need to apply toHTMLElement. 
Element has setFocus.

Done.

We don't need to check it.  setFocus(false) don't change
Document::focusedElement value.

[Habib Virji, 2014/03/31 09:30:15]

Done.

Because we called setFocus(false) on page blur, we should call setFocus(true) on
page focus.
