Since "Bug 695480 - Remove support for Chrome -> Content leaks" landed
...I am now seeing bunch of "TypeError: can't access dead object".
This sounds good in general (since useful for mem leaks), but I am
also seeing the exception for the following code:
var object = gBrowser.selectedBrowser.contentWindow.wrappedJSObject;
var parent = Object.getPrototypeOf(object);
Object.keys(parent); // EXCEPTION
If the object is set to be
"gBrowser.selectedBrowser.contentWindow" (no wrapper) it works.
Is it expected? Is it reported?
