Can I safely set z-index: auto to [data-overlayscrollbars-viewport] element?

Firstly, thank you for this beautiful library!

Describe the bug
I have some fixed block with z-index: 10 and with scrollable content inside. Also I've got one more fixed element inside this scrollable content, which overlapping by scrollbar. It can be solved by setting z-index: auto to [data-overlayscrollbars-viewport] element, but I'm not sure it doesn't have any unintended consenquences.

Examples

To Reproduce
Steps to reproduce the behavior:

1. Go to block and scroll down
2. See block being overlapped by scrollbar

Good day @hatttfu :)

Changing z-index should be purely cosmetic change and if it works for your usecase there shouldn't speak anything against it
