    [shell] Propagate key events from EvWindow to EvView
    
    EvAnnotationWindow is a GtkWindow that doesn't accept focus, but we
    manually grab the focus on the text view contained in it to be able to
    modify the annotation contents. We need to propagate the key events to
    the view even when the view is not the focused widget. The view will
    only handle these events when there's a popup window with the focus so
    that it's possible to type in window annotations.
