Description Yury Semikhatsky 2012-01-31 01:49:03 PST

Open attachment and take a heap snapshot. Then click "Add listener" button and take another snapshot. Find 'myEventListener' function in the heap view.

Result:
According to the profiler it is only held by a global weak handle.

Expected:
Strong reference from corresponding DOM object group/DOM node to the closure object.
