wheel & mousewheel event handlers don't work together

Reported by m.go...@gmail.com, Apr 4 2016 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.110 Safari/537.36

Steps to reproduce the problem:
1. Open http://jsbin.com/vifego/edit?html,css,js,output
2. Scroll the page
3. 

What is the expected behavior?
Both counters should increase.

What went wrong?
Only the first counter increases. If you comment out the first event handler (the `wheel` one) & scroll the page the second counter increases.

Did this work before? N/A 

Chrome version: 51.0.2699.0  Channel: canary
OS Version: OS X 10.11.4
Flash Version: Shockwave Flash 21.0 r0

Safari 9.1 & Edge 13 behave in the same way. IE 11 doesn't exhibit the issue.

Able to reproduce the issue on windows 7, Linux Ubuntu 14.04 and Mac 10.11.3 using chrome version 49.0.2623.110 and canary 51.0.2700.0.
This is non regression issue as the issue observed from M30 builds.
Hence marking it as Untriaged.

Thanks,

FireFox and Edge do exactly the same thing. This is to prevent a double registration firing problem.

If you want you can mix them on different targets but not on the same target. ie; if you move one to be a window.addEventListener instead of a document.addEventListener it will work.
