--- Comment #4 from Joseph Pecoraro <joepeck at webkit.org> ---
Geoff and I debugged this for a bit, and it looks like this is okay. For one, eventually in the test the object does get cleaned up so long term that looks fine. But further investigation into why it was temporary alive, it looks like the object is alive because it is on the stack during collection. Adding a "timeout" between the map mutation and collection, the object goes away as expected!

Closing as behaves correctly.
