I have IE compatibility code that uses __defineGetter__ on Event this code is 
broken in 1.0.3. I have quite bit of this sort of code (on things other than 
Event as well) so I am looking to understand: 
A) Was this intentionally changed? (I couldn't see anything explicit in the rel 
notes and from my reading of the related bugs (289074 & 289083?) it doesn't seem 
like they should disable this)
B) And if this is really correct then what is the complete nature of the 
nerfing?  I am trying to figure out what exactly I need to change in my code to 
fix this. 

On 1.0.3 the following example shows Error: uncaught exception: [Exception... 
"Illegal operation on WrappedNative prototype object" nsresult: "0x8057000c 
(NS_ERROR_XPC_BAD_OP_ON_WN_PROTO)" location: "JS frame :: http://localhost:8080/
test/ffbugs/bug1.html :: anonymous :: line 5" data: no] in the console 

<html> 
<head> 
<script type="text/javascript"> 
Event.prototype.__defineGetter__("srcElement", function () { 
return this.target; 
}); 

function doOnCtxt(event){ 
window.alert(event.srcElement.tagName); 
} 
</script> 
</head> 
<body> 
<div style="height:500px;width:500px;position:relative;background-color:blue;
color:red" oncontextmenu="doOnCtxt(event);return false;"> 
right click me! 
</div> 
</body> 
</html>
