[Question] How to work with vendor prefixes

Hey, thanks for the awesome work!

Is there a way to use vendor prefixes such as `::-webkit-scrollbar-track` and others?

Thanks again?

The issue asks whether vendor-prefixed selectors such as `::-webkit-scrollbar-track` are supported, but names no file, test, or entry point. Check the relevant documentation or implementation, then provide a confirmed usage path or turn the question into a clearly scoped documentation change.
