// Creates a Blob URL for an HTML document that fetches itself and sends the result to the
// specified response queue UUID. This is somewhat contrived but aims to test a more common
// scenario where a Blob URL with a video/audio mime type is navigated to and has an HTML document
// created for to allow media controls to be present. In that scenario the Blob URL will be used
// via a "src" attribute, resulting in a first-party resource load.
