Details

(Whiteboard: [gfx-noted][platform-rel-Google])

Tested on FF Nightly 55.0a1(2017-04-03) Windows 8.1 x64 with a touchscreen. 


STR:

1. Open FF and go to https://docs.google.com/spreadsheets/d/1VCk6LAJ9g-El9e61cDzoysHahMU6wc3Qo2bPvau6frY/edit#gid=0

2. Using the touchscreen drag the slider from the scrollbar and move it up and down.

Expected results: The slider and the page are moving. 

Actual results: Only the slider moves and the page doesn't react to the scroll. 


Note:
This issue is not reproducible all the time. 
I changed the apz.drag.enable pref and the bug is still there.

Per comment 0 this happens with and without apz.drag.enabled, so this does not block async scrollbar dragging.
No longer blocks: async-scrollbar-drag
Using Microsoft Surface Pro 2 device (Win 10 Insider Preview build) and latest Nightly 58.0a1 or Firefox 57 Beta 5 shows the following results:
- dragging the scrollbar down or to the right (bottom scrollbar) does nothing in the first place
- lifting the finger and then dragging the scrollbar up, respectively to the left (bottom scrollbar) scrolls the google sheet in the opposite direction: up when scrolling down and down when scrolling up

So this works on arm64/touchscreen laptop, but is just rather slow, and it is slow because of JS.
