        Fix for http://bugs.webkit.org/show_bug.cgi?id=12599
        <rdar://problem/4973507> REGRESSION: When replying in Gmail, the caret disappears when you start to type (12599)

        When a frame's window was focused, the page didn't get updated about the new frame getting focus.
        This was causing handleKeyPress to fail because it kept getting a selection for the wrong frame (which wasn't editable).
