Video Tag - Timeupdate event is getting fired on video src change

Reported by nikhilmi...@gmail.com, Feb 18 2017

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36

Steps to reproduce the problem:
1. Open following code https://jsfiddle.net/saocbmz4/2/
2. Check that after 5 second when source is changed timeupdate is also triggered

What is the expected behavior?
As no time is changed it should not happen. Same behavior is not observed in other browser - firefox, edge.

What went wrong?
When video tag src is changed timeupdate event is also getting triggered. Same was not happening in chrome earlier version

Did this work before? Yes 55

Chrome version: 56.0.2924.87  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 24.0 r0

Thanks for the report & jsfiddle.

Using the per-revision bisect providing the bisect results,
Good Build: 56.0.2908.0 (Revision: 429486)
Bad Build: 56.0.2910.0 (Revision: 430103)

You are probably looking for a change made after 429636 (known good), but no later than 429637 (first known bad).
CHANGELOG URL:
The script might not always return single CL as suspectas some perf builds might get missing due to failure.
