I don't remember the history off hand, but I think the issue was that much of 
the Node contract it couldn't implement (maybe because in reality it was a 
popup window, not a Node), and so instead of lying about it we fessed up and 
said it was something different.

All tooltips should behave as you describe by default and should never grab 
mouse events. Is there not a JIRA for that?
