[Performance tab] nodes leaking on focus

Reported by bmsd...@gmail.com, Jul 24 
UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36

Steps to reproduce the problem:
1. goto: https://codepen.io/bmsdave/pen/ajWaKX (or download https://bmsdave.github.io/bugs/nodes_leaking_on_focus.html and try it local)
2. open DevTools (Preformance tab)
3. Collect garbage
4. Start Record
5. Click button "Click me"
6. wait 2 second
7. Collect garbage
8. Stop Record

What is the expected behavior?
Count of nodes after click "Click me" = count of nodes before click

What went wrong?
Count of nodes after click "Click me" != count of nodes before click

Did this work before? N/A

It looks like fixed in Canary.
@alph, do we instrument node allocations for memory allocation timeline profiler?
If I remove ".remove()" from code snippet I can see leaked nodes on timeline but I can not get allocation stack for them and got something like this object as allocated before profiler was started. Is it expected behavior?
