Strange behavior when zoom set to 200%

Reported by paul...@gmail.com, Sep 15 2016 
UserAgent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.113 Safari/537.36

Steps to reproduce the problem:
1. Set zoom to 200%
2. See my issue on github (https://github.com/gaearon/react-dnd/issues/537)
3. Go here: http://gaearon.github.io/react-dnd/examples-drag-around-naive.html drag around the boxes this didn't happen in previous version of chrome and it doesn't occur in Edge/Firefox

What is the expected behavior?
Chrome needs to account for zoom (high resolution displays)

What went wrong?
I believe chromes coordinate system is not calculating the correct x/y position when monitor has zoom

Did this work before? Yes Previous version of Chrome (52)

Chrome version: 53.0.2785.113  Channel: stable
OS Version: 10.0
Flash Version: Shockwave Flash 23.0 r0

Unable to reproduce the issue on Windows 10, MAC 10.11.6 and Ubuntu 14.04 using the reported chrome version #53.0.2785.113, chrome stable #53.0.2785.116 and latest canary #55.0.2860.0.
Attached a screen cast for your reference.

Following are the steps followed to reproduce the issue.
------------
1. Navigated to url http://gaearon.github.io/react-dnd/examples-drag-around-naive.html
2. Zoomed the page to 200%.
3. Dragged around the boxes.
4. Observed that the boxes return to their original coordinates when dragged out of the box. Hence, working as expected.

This step is wrong

"Zoomed the page to 200%."

Please don't zoom using the browser. You must use windows display settings and set the Increase the zoom there. My lenovo defaults to 200% zoom when I adjust down to 100% it works again.  Note you must logout/login for changes to take affect.
