Objects that carry event listeners and can be created more than once (like pop-up windows) may be affected by the garbage collection delay. Removing these objects is not a guarantee that their event listeners will stop right away.
It's not fully known how critical issues generated by this problem can be. I believe the best thing we can do is removing event listeners before throwing away those objects.
