Is this about Timeline?

It's not relevant to Timeline. We're adding user input recognition which is outside rendering process.

mushan@Could you please provide sample file or code with actual and expected behavior screencast for further triaging the issue.

ssamanoori@ the CL is here: https://codereview.chromium.org/1984173002/

I can not assign mushan@ as an Owner because he isn't member of chromium, but let me change the status to Started because his change is under review.

Bryan: Can I assign you to this because you are reviewing his change?

When I wasn't a committer yet, I could assign myself to work on any bug to send a patch, IIRC. But current system seems to allow nothing for non-committers other than writing comments.
