`api/abort/serviceworker-intercepted.https.html`	Timeout	10 / 12	TEST BUG	the iframe of the test navigates to the scope of `sw-intercept-abort.js`, whose fetch event of the navigation request waits for the abort of its signal: the iframe never loads, so `with_iframe()` never resolves and the test times out (as in the browsers on wpt.fyi, 10 of 12 subtests with a TIMEOUT). The signal of the request of the fetch event is aborted with the serialized abort reason of the fetch

The multipart/form-data encoding (RFC 7578) writes the close delimiter `--boundary--` even without entries, which `fetch/api/response/response-form-data.html` ("Empty form data") and the round trips of `fetch/api/body/formdata.any.js` require: the two expectations cannot both be met
