   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.

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