Duplicate events also happen when tabbing to the input, not just via mousePress. This makes me think there is a more generic problem. It seems to me that if the focus changed during the dispatchEvent, than later on during the setSelection path, the node should not dispatch a focus event. Or maybe it should never at all. I have to learn more about what is going on.
