Wheel event doesnt work on IE11 with horizontell scroll

Wheel event doesn't work on IE11 with horizontell scroll, but it works on vertical scroll. Tested on the demo scroll, same thing there.

Ahh maybe this is because its not like that in a native scroll. But it strange that it works in chrome thou.

I kind of fix this for ie11, by always using deltaY. But I guess it will break if the mouse has a X and Y scroll

[iamrane]

wheelSpeedDelta = -(evt[deltaDir] || evt.detail || (-1 / 3 * evt.wheelDelta) || evt['deltaY']) / 40;

I guess did the trick
