Merge 183455 "Focus unfocusable node upon reference fragment nav..."

> Focus unfocusable node upon reference fragment navigation
> 
> Currently, when the page navigates to a non-focusable reference fragment,
> the currently focused element does not change. In Firefox/IE, the focus is
> moved to the referenced element even when this element is non-focusable.
> 
> This mismatch in behavior became apparent when Blink started supporting
> a:focus (https://crbug.com/388666). In IE/FF, clicking on <a href="#ref">
> causes the link to loose focus, and therefore :focus does not get applied
> any more. In Chrome, however, :focus remains activated because the focus
> does not change.
> 
> This patch changes the behavior of Blink: When the pages navigates to a
> reference fragment that refers to a non-focusable node, then the focus
> is removed from the previously focused element.
