So when the JavaScript engine executes web page script, and the script 
sets some element properties dynamically, and Gecko is informed, and the 
CSS rules engine chimes in, and the content is reflowed by Gecko, 
--during that entire sequence, there are no consumable notifications 
available via any API at all?  Does it make a difference if an XPCOM 
component is doing the listening, as opposed to a sandboxed web page? 
(i.e., creating some sort of proxy interface as is sometimes done with 
network channel listeners.)
