/*
 * DEPRECATION NOTICE: This workaround is no longer needed. You can now use ESM packages with Remix by 
 * tracking all ESM packages in your remix.config.js file. This means we can now use react-markdown
 * and are not required to reimplement everything from scratch.
 * Find a nice example implementation here: https://stackblitz.com/edit/node-ydjuwx?file=remix.config.js

/* 
 * react-remark does not support cjs anymore but Remix.run will not work with esm just yet (without async imports)
 * Unfortunately, the older versions of react-remark do not implement useRemarkSync
