Chrome: 69.0.3472.0 (Official Build) canary (64-bit) (cohort: Clang-64)
JAWS: 2018
NVDA: 2018.2.1

Steps to repro:
# With JAWS running, open two tabs in Chrome and load two different sites 
# On the first tab, move to about the middle of the page with down arrow
# On the second tab move to the end of the page with ctrl+end
# Switch back to the first tab and use arrow keys to verify the virtual cursor's location
# Notice that you are at the top of the page
# Switch to the second tab and verify location with arrows
# Notice that this tab too has reset it's position to the top of the page

Expected: JAWS should keep it's cursor location in each tab

Actual: Cursor is reset to top on tab change
