[whatwg] Comparing mouseover/mouseout, mouseenter/mouseleave and dragenter/dragleave

In Firefox 4 dragenter/dragleave are fired like mouseover/mouseout 
events - when you enter or leave the elements irrespective of whether 
the mouse pointer is entering a child element or leaving the element 
altogether.  So I have two questions:

1. Is Firefox 4 doing the correct thing?
2. If it is doing the correct thing, isn't it a bit confusing that 
dragenter doesn't behave like mouseenter but like mouseover and 
dragleave doesn't behave like mouseleave but mouseout?

The phrase "Fire a DND event named dragenter at the immediate user 
selection" seems to indicate Firefox is correct, but it wasn't the 
behaviour I was expecting when I tried it for the first time.
