This information is embedded within the algorithm for constructing interfaces and their prototypes in the section for ECMAScript glue in the WebIDL spec... This really *should* make the `wasm_bindgen_backend::ast::ImportType::extends` member from a `Vec<Ident>` into a `Vec<syn::Path>` so that we could use `js_sys::Object` in the extends field, but that is a huge pain because then the `ImportedTypes` trait needs to be changed, and all of its implementers, etc...
