Firefox+Windows: Slimscroll scrolls whole page

[PinkTiu]

Hey,

if you hover over the slimscroll content and start to scroll not only the slimscroll content is moving but also the whole page. This feels a bit strange. The expected behavior would be that only the slimscroll content scrolls and the page does not.

This only happens in Firefox running under Windows. In Chrome and Edge this works fine. With Firefox running under macOS or Linux this works fine, too.

You can fix the problem the following:
After line 394 in the current source code you have to add
target.addEventListener('MozMousePixelScroll', _onWheel, false);
This solves the problem for me.
