I'm developing and managing hybrid apps.
Suddenly android users says infinite scroll feature didn't work frequently.
So I tested infinite scroll example serveral chrome versions and I make test.

I found javascript scrollTop value is strange.
Only Android Chrome 71 has a problem.
So browser(webview) cannot recognize the end of scroll.

I attached my test file and screenshots.


Device name: LG V20 (LG-F800S), Samsung Galaxy S7(SM-G930K)

From "Settings > About Chrome"
Application version: Chrome stable 71.0.3578.99
Operating system: Android 8.0

URLs (if applicable): 
http://scrollmagic.io/examples/advanced/infinite_scrolling.html

Steps to reproduce:
(1) open test.html
(2) chrome debug and scroll until the end
(3) scrollTop value strange only in 71.0.3578.99
so infinite scroll example doesn't work


Expected result:
LG V20

scrollTop = $(window).scrollTop();
docHeight = $(document).height();
winHeight = $(window).height();

scrollTop + docHeight = winHeight
chrome 70
4094           518        4612
chrome 71
4005           518        4523

Actual result:
chrome 71
4004.75        518        4523

PC(70,71) and Android(70) works it.
