    <thetext>This is a bug detected in bug 84908. In a nutshell, an onresize event handler in the popup window can be non-deterministically reclaimed by GC. For more details, please look at the chromium issue 123642: http://code.google.com/p/chromium/issues/detail?id=123642

The patch for bug 84908 fixes V8LazyEventListner.cpp so that an event listener object is re-created if the event listener object is already reclaimed. This is just a temporary fix. We should fix the code so that an alive event listener object is never reclaimed. Please look at bug 84908 and chromium issue 123642 for more details.</thetext>
