Hi… I have a simple ember app that does data-down to a component

I basically want to avoid memory leaks in my app. I tested in canary and found that there are detached HTMLDivElements… Below is the screenshot… Are these really memory leaks?

I did the following:

1. Took a heap snapshot after loading the twiddle (snapshot1)
2. Clicked on Show/Hide child button to show the child component
3. Clicked on Show/Hide child button to hide the child component
4. Took a heap snapshot ( snapshot 2 ) Compared the snapshots and found the following
