These tests set up a delayed echo endpoint using a synchronous XHR to http://127.0.0.1:PORT/echo, but the page itself is served from http://localhost:PORT. This cross-origin request triggers a CORS preflight, which intermittently fails with a NetworkError. There's already a FIXME in place to get rid of the spin_until() that caused this to happen. Use a relative URL instead, since the page is already served from the echo server. Fixes #8564
