opening many youtube tabs causes Chrome Helper to get stuck in 100+% CPU usage

Project Member Reported by marhar@google.com, Nov 1 2016 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36

Steps to reproduce the problem:
- run Chrome on Mac (El Capitan)
- go to Youtube main page
- command click on videos to open them in new tab
- after about 15 tabs opened, Chrome slows down a lot
- looking in Performance Monitor, there is a "Chrome Helper" running at 100+% CPU
- Kill that process, all YT tabs get the sad face, and everything returns to normal.
- interestingly, reloading all those pages doesn't cause the 100+% Chrome Helper to return

What is the expected behavior?
Chrome does not slow down, or I get some warning that Chrome is overloaded.

What went wrong?
A Chrome helper process goes into 100+% CPU usage until it is killed.

Did this work before? Yes ?

Chrome version: 54.0.2840.71  Channel: stable
OS Version: OS X 10.11.6

Please provide us with more information:

1) Take a sample of the process at 100%+ using activity monitor.
2) Take a trace using chrome://tracing.
