Continuous scrolling using scroll wheel click, then rolling the scroll wheel

Reported by navidgow...@gmail.com, Oct 28 2017 
UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36

Steps to reproduce the problem:
1. Open any webpage that can be scrolled
2. Click the scroll wheel and move the mouse down. The page will start scrolling
3. Rotate the scroll wheel.

What is the expected behavior?
The page should continue to scroll because of the scroll click and the mouse movement, even after rolling the scroll wheel

What went wrong?
The page now scrolls one line once the wheel is rolled once, and doesn't continue scrolling in the direction which the scroll was initiated with the previous action

Did this work before? Yes Before the latest update, so I assume before chrome 61

Chrome version: 61.0.3163.100  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 27.0 r0

Able to reproduce this issue on Windows-10 using chrome latest stable #62.0.3202.75 by following steps mentioned in the original comment.

https://chromium.googlesource.com/chromium/src/+log/61.0.3132.0..61.0.3133.0?pretty=fuller&n=10000

From the above change log suspecting below change
https://chromium.googlesource.com/chromium/src/+/5971e47dc08dbb773f58fd6fb13b1df7917fd295

Note: Unable to provide python tool bisect to provide minimal CL, all the builds which invoked during the bisect was good, hence providing manual CL.

aelias@ - Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!

Apologies for not mentioning the latest behavior across all channels. Yes, able reproduce this issue on chrome latest beta #63.0.3239.18, dev #64.0.3251.0 and canary #64.0.3253.0 channels as well. 

Note:

Thanks!

I only reviewed the IPC change, deferring to bokan@ who knows the code better than I do.

Yes, this is likely introduced by aelias@'s refactoring of autoscrolling and aelias@ is transitioning off Chrome.

sunyunjia@, could you please take a look at a fix (I'm traveling over the next two weeks and don't have a Win machine)? I suspect we just need to take account of the new autoscrolling state when handling mouse wheels.

This appears to be fixed - likely by one of sahel@'s changes.
