Steps to reproduce the problem:
1. Open URL (www.espn.com) in Chrome Beta (58.0.3029.42)
2. Leave Chrome Beta (home screen, another app, turn screen off, etc)

What is the expected behavior?
CPU usage will not be high after leaving Chrome.

What went wrong?
Pixel XL running Android 7.1.1 and 7.1.2

I typically run Tugabrowser but have trouble logging in to some sites so I switch to Chrome for those. Within the past few versions of Chrome Beta, once I leave Chrome my phone has felt warm to the touch. Using the System app to monitor system resources I see that the CPU usage remains around 50% when it typically sits at under 5% when I'm doing nothing with the phone. This appears to only occurs after I have opened Chrome. I can sometimes get the phone to idle properly by force closing Chrome Beta but it isn't a guaranteed fix. Rebooting the phone appears to be a consistent fix for this problem.

This does not occur after using the current stable release, Chrome 57.0.2987.132

Did this work before? Yes 57.0.2987.132
