IAccessible2::accLocation incorrect when page is zoomed from touch screen

Project Member Reported by mike.hil...@gmail.com, Feb 27 2018

Issue description

UserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/64.0.3282.186 Safari/537.36

Steps to reproduce the problem:
1. Use a PC or laptop with a touch screen.
2. Run a AT product such as Zoomtext which highlights the focus location on the web page.
3. Launch Chrome and load a page.
4. Tab around and note that Zoomtext highlights the object.
5. Zoom into the page by pinching to zoom on the touch screen. (if using Zoomtext then you may need to change zoomtext touch mode to allow this).
6. the focus hilight has not changed to follow the zoom level and if you continue to tab around it acts as if the page is not zoomed at all.

What is the expected behavior?
When the page is zoomed, the location should be updated in the iaccessible tree and EVENT_OBJECT_LOCATIONCHANGE events should be fired for all visible objects.

What went wrong?
pinch to zoom is ignored by the location calculation in the accessibility tree.

Note, zooming by changing the font scale with Ctrl+mouse Wheel does work correctly.

Did this work before? N/A 

Chrome version: 64.0.3282.186  Channel: stable

Thanks for filing the issue!

@Reporter: Could you please share a sample test file/URL which helps us to triage the issue in a better way, as ET team is not very clear about running an AT product. Any further inputs from your end may help us.
It doesn't matter what URL you choose, the bug occurs on all pages.
