[pointerevents] Simultaneously move / drag with multiple pointer devices

mingchou has just created a new issue for 
https://github.com/w3c/pointerevents:

== Simultaneously move / drag with multiple pointer devices ==
Wondering if spec should say something about the behavior of 
controlling multiple input devices simultaneously? For example, what 
is expected when dragging some item with mouse then click the button 
on pen?

Tested OSs behaviors (with mouse and pen), and the results are
1) Windows 10
   The dragging item can be moved by another input device
   Button down & up from another input device can cancel the button 
pressed state (stop dnd as well)

2) Linux 16.04
   The dragging item can be moved by another input device
   Button down & up from another input device can't cancel the button 
pressed state (nor stop dnd)

3) Mac 10.11.5
   Similar to Windows 10.

Tested Chrome Canary on Windows10 and it behaved the same as Mac and 
Windows10.
Tested Edge on Windows10 and the dnd is not impacted by another input 
device. In that case, dnd doesn't work with the 2nd input device but 
click works.
