Credit
This library is a fork of @reach/auto-id
Why fork?
Reach UI doesn't use real semantic versioning (each of their packages updates versions at the same time regardless of
changes to individual packages... nonsense) so it's possible (and annoyingly so) that you could easily wind up with duplicate
version of the auto-id package in your bundle. Lastly, the Reach library throws super annoying warnings
in SSR because it uses useLayoutEffect. This library uses @react-hook/passive-layout-effect
to avoid that.
