Description
Describe the bug
I have a double scrollbar in Firefox on Windows. On Linux it's all fine.

To Reproduce
Here the customized simplebar.css: https://gist.github.com/Johnnii360/12e8e96bbcc5effd2db017892dc41c81
Expected behavior
Just only the Simplebar visible.
Reproducible example
See above. Due to customization difficult to jsfiddle.
