Google Chrome 69.0.3494.0 (Official Build) dev (64-bit), Firmware Version	Google_Eve. 9584.160.0

Steps to reproduce: 
# Flip convertible ChromeVox into tablet mode
# Turn on ChromeVox by holding both hardware volume keys for 5 seconds 
# Load a page with text such as https://en.wikipedia.org/wiki/Platypus
# Attempt to scroll up and down using two fingers (or even three fingers)
Expected: able to scroll so I can get to the bottom of the page to explore by touch
Actual: no way to scroll pages

(A further extension would be respecting traditional vs Australian scrolling per system settings)
