The blur event is not fired on an <input> within an <iframe> when the input
loses focus by programmatically focusing the window.

In particular, suppose there is an <input> within an <iframe> and perform the
following actions programmatically (in order):

1) Call focus() on <input>.
2) Call focus() on the current window.

Then the following sequence of events are fired, where an event := (event
target element, event type):

(window, blur), (<iframe>, focus), (<input>, focus), (<iframe>, blur), (window,
focus).

Notice, the event (<input>, blur) is missing from this sequence. The expected
result is:

window, blur), (<iframe>, focus), (<input>, focus),  (<input>, blur),
(<iframe>, blur), (window, focus).

By the unfocusing steps listed in section 6.4.2 of the HTML 5 spec.
<http://dev.w3.org/html5/spec/Overview.html#focus-management>, we should fire a
blur event at <input>.
