           Summary: DOM Document adoptNode doesn't always connect event

            Status: NEW
          Severity: Normal

If a Node containing an event handler is moved from one document to another, the event handler might not be registered with the new document if the old document has already been destroyed.

This appears to be due to some optimizations in the Node::didMoveToNewDocument" that check the original document for event handlers, and assume there's nothing to do if they have been purged. Unfortunately, this can cause us to fail to add event handlers when expected.
