Mac Firefox >= 56 (and possibly more) scrolling a column set horizontally is broken

[buggedcom]

Scrolling column sets appears to be broken on mac firefox >= 56, and possibly more. I haven't tested further since this is a significant number of versions already.

We had a report with out new beta site that column set based grids were not scrolling the column sets on Mac Firefox 59 with a trackpad or magic mouse.

I used this page as a base http://dgrid.io/js/dgrid/test/complex_column.html to ensure that it was not our code layer interfering with dgrids, I went back from firefox 59 through to firefox 56. And it is broken for all.

A side note is that if you first scroll vertically and then without releasing the scroll device start scrolling horizontally that works fine on all versions.

Seems like this is a bug within firefox itself, or at least the intended functionality of scrolling horizontally with the wheel event in firefox.

Take this http://jsfiddle.net/buggedcom/mr4xn2r1/ for example. In Chrome/safari the event fires if scrolling horizontally or vertically, however in firefox only fires once
