Create an iframe (outter-iframe) with designMode=on and add to its document, another iframe (inner-iframe).  Set inner-iframe's src to point to a page that has javascript.  The javascript inside inner-iframe is disabled.  I am not sure if this is intended by design.  But for what I am trying to accomplish, it'd be great if inner-iframe's javascript isn't disabled.  Perhaps providing an iframe attribute that specifies whether its javascript should be disabled would be great.

Reproducible: Always

Steps to Reproduce:
1. Create an iframe (outter-iframe) with designMode="on"
2. Insert into outter-iframe, another iframe (inner-iframe)
3. Set inner-iframe's src to some page that has javascript
4. The page displayed in inner-iframe has all javascript disabled.

Actual Results:  
The inner-iframe's javascript are disabled.

Expected Results:  
The inner-iframe's javascript should be enabled (or can be controlled via special attribute) whether it's placed inside a normal iframe or an editable iframe.

I found that FF disable only JS events that set in html like 
<input type="button" onclick="alert(1);"> 
or from JS, like:
var o = document.createElement('input');
o.type = 'button';
o.onclick = function () {aleft(1);};

But if you use method addEventListener JS will be work.

So this example will works:
var o = document.createElement('input');
o.type = 'button';
o.addEventListener('click',function () {aleft(1);},true);

I created some tests to demonstrate this at:

PVOID: I can't duplicate that javascript.  It seems even a document.write or an alert() will not get called.
