Steps to reproduce the problem:
1. Launch Chrome (64-bit) Windows (Win7, Win8.1)
2. Navigate to YouTube.com 
3. In YouTube.com search field, type (at fast rate) a search string

BUG--> While typing the search string, the keyboard focus is suddenly lost and my previously typed search string text is suddenly deleted.

What is the expected behavior?
Chrome shouldn't suddenly lose focus when typing in data.

What went wrong?
While typing, the input box in YouTube.com (and other similar sites) suddenly loses focus and my previously typed data is deleted (as if the input field was suddenly reset.)

Did this work before? Yes I think in Pre-53.x Chrome builds... just started happening recently

Chrome version: 53.0.2785.116  Channel: stable
OS Version: 6.1 (Windows 7, Windows Server 2008 R2)
Flash Version: Shockwave Flash 23.0 r0

This bug happens so fast that it's nearly impossible to track down and analyze without it happening first.  It has just started happening recently in Chrome.  I've seen this on several different web sites, such as YouTube.com and others where there's an input box (search field.)  I'd appreciate any suggestions on how to setup Chrome for debugging this issue PRIOR to it happening again...

Thanks!
