Woah, `ref` as a function is secretly so powerful. No more `undefined` checks and useEffects just to add some document event listeners. Handle everything with a function in-line 👍

unless refs changed while i wasn’t looking you need to wrap this in `useCallback`, otherwise it’ll call both the cleanup and setup function again every single render

The compiler won't wrap an inline function here in useCallback for you because it changes semantics. /cc @gsathya.bsky.social

It should work the same though

Hmm isn't it the same as having a useEffect without dependency array, and then adding an empty one to it? That changes st which time / how often it runs.
