Clarify why certain tests disable the React Compiler

With the React Compiler, our component code is transformed at build time to automatically apply various forms of memoization. This changes the runtime semantics of our code a little bit and therefore could surface new bugs in the next release cycle in case any components fail to follow the rules of React. See https://react.dev/learn/react-compiler for more information.

This results in a small bundle size increase and modest performance gains, but I think it's worth it given the potential for larger performance gains once we tune the component structure a bit more.
