Steps to reproduce the problem:
1. open the following URL: https://jsfiddle.net/t86zvows/1/
2. open the Chrome dev tools, and turn on the mobile device toolbar so that the page is opened as if on a mobile device
3. open the console
4. click anywhere inside the yellow rectangle

What is the expected behavior?
clientX value of the pointerdown event matches the clientX value of the click and touchstart events

What went wrong?
clientX value of the pointerdown event does not match the other clientX values at all

Did this work before? N/A 

Chrome version: 64.0.3282.140  Channel: stable
OS Version: OS X 10.13.2
Flash Version: 

This is either a bug, or me misinterpreting the pointer event standard ;-)
