LazyPromise
/**
* A LazyPromise doesn't run its executor until .then, .catch, or .finally is called,
* or the promise is awaited.
* Unfortunately, `@endo/promise-kit`'s isPromise returns false for instances of LazyPromise.
* However, LazyPromise instances will return true for instanceof Promise.

// Note: However, accessing iframe.contentDocument does throw a SecurityError so iframe.contentDocument.write is not possible.

// Problem
