A handful of other pages are also affected, I've seen:

• https://react.dev/learn/referencing-values-with-refs
• https://react.dev/learn/synchronizing-with-effects
• https://react.dev/learn/separating-events-from-effects
• https://react.dev/learn/removing-effect-dependencies

Minified error is suggests a property code is unsafely read somewhere.

TypeError: can't access property "code", d[P.uu] is undefined

Edit: This is the only candidate I'm seeing at a glance where that would be read.

Edit 2: Many MD files touched in #7989 earlier today appear to be affected.

Thanks for reporting, I'll take a look!

Going to revert the docs changes first while I investigate: #7995
