Out of curious, is it called actually? IIRC, MessageCenterController methods of
MessagePopupCollection are called from only ToastContetsView but you don't call
this method from ToastContetsView.

Good catch~! I've updated the ToastContentsView method to forward the callback
to here like the other methods in ToastContentsView. Toasts still seem to
properly resize.
