// The typings around the exports below are a little funky:
//
// 1. We want the `name` of the shim classes to match the real ones at runtime,
//    hence e.g. `class Element`.
// 2. We can't shadow the global types with a simple class declaration, because
//    then we can't reference the global types for casting, hence e.g.
//    `const ElementShim = class Element`.
// 3. We want to export the classes typed as the real ones, hence e.g.
//    `const ElementShimWithRealType = ElementShim as object as typeof Element;`.
// 4. We want the exported names to match the real ones, hence e.g.
//    `export {ElementShimWithRealType as Element}`.
