classicruntime, it's easy to import polyfills needed by React: you first import the polyfill, and then React itself. However, with theautomaticruntime, thereact/jsx-runtimeimport is always injected at the top and thus it's not possible to manually control the imports order.This PR changes it so that

However, it's a problem with commonjs sincerequirecalls are not hoisted and not always statically analyzable: when using CJS with theautomaticruntime, you'll need to load the polyfills in an entry point that doesn't contain JSX code.This PR adds a new feature to
