Move mouse as scroll bar moves up on an infinite-scroll page

Reported by runem...@gmail.com, Jan 9 2017 
UserAgent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36

Steps to reproduce the problem:
1. Go to a page with infinite-scroll (adding content while scrolling down)
2. Scroll to the bottom using the scroll bar

What is the expected behavior?
As content is added and the scroll bar moves upward and becomes smaller, the mouse should follow it. The new mouse position should be newScrollBarPosition + newScrollBarHeight*(oldMousePosition - oldScrollBarPosition)/oldScrollBarHeight

What went wrong?
The scroll bar moves upwards but the mouse stays at the same place, making scrolling down or scrolling back up more difficult. 

Did this work before? No 

Chrome version: 55.0.2883.87  Channel: stable

Try to scroll all the way down on http://jsfiddle.net/vojtajina/U7Bz9/. The first time the scroll bar jumps up, the mouse stays at the same spot. The second time content is added, you get back to the top of the page and can't keep on scrolling. The Facebook news feed is another example of this.

Unable to reproduce this issue on Windows-10 using chrome latest stable M55-55.0.2883.87 by following  steps mentioned in the comment #2, Observed no issues in scrolling the page continuously in provided test case and including Facebook feed as well.

runemoro@ Thanks for the test case, Are you able to reproduce this issue consistently including incognito mode? Could you please recheck this issue by creating a new profile under chrome://settings with no apps or extensions in your browser. If issue still persists please check the same on chrome latest canary M57 and kindly update this bug.

Thanks!
