Oops, not sure why the text was lost in the WF2 merge.

I've added equivalent text back. It describes the Opera/IE behaviour; 
could you elaborate on why the WebKit behaviour is better?

Authors can emulate the WebKit behaviour if they really want it by just 
calling .click() on the element they want to have activated when the 
target is focused.
