Example URL:
http://html5videoformatconverter.com/html5-video-tag-example.html

Steps to reproduce the problem:
1. Open link http://html5videoformatconverter.com/html5-video-tag-example.html
2. Start video playing (if it was not started)
3. Minimize/expand window (or switch tabs).

What is the expected behavior?
Video will continue to play (without freezing), like in the last Google Chrome version 58.0.3029.110.

What went wrong?
Audio continues to play good but video sometimes freezing.

Did this work before? N/A 

Is it a problem with Flash or HTML5? HTML5

Does this work in other browsers? Yes
