The scroll() method of elements doesn't work properly in Firefox when the smooth behavior is enabled. It works fine in Chrome and Edge.

It seems like the scroll event is interrupted by some other listener as it still moves a bit. Both behaviors can be checked in the example Pen above.

I was able to trace it down to this line: https://github.com/mdbootstrap/perfect-scrollbar/blob/1.5.1/src/update-geometry.js#L86 When it's commented out everything works as expected, but I'm not sure why exactly the scrollLeft property affects smooth scrolling.
