Firefox , IE and Edge native scrollbar

[mrlouissimion]

On IE and MS Edge the native scrollbar was always appearing behind the scrollbar-macosx.

Solution for IE and EDGE:
Adding to .scroll-wrapper{
-ms-overflow-style : none
}

For Firefox on Windows 10 the native scroll look is showing behind the scrollbar-macosx. Any fix for this?
I am using Bootstrap v 3.3.7

Just to make sure it's really scrollbar issue - can you check if behavior is the same on demo page?
