According to the spec
https://html.spec.whatwg.org/C/#timer-initialisation-steps
setTimeout()/setInterval() don't inherit
initiating script's muted errors flag,
which matches with Chromium/Firefox/Safari.

This CL fixes WPT tests to match with the spec/impl, i.e.
to expect errors from setTimeout()/setInterval()
from cross-origin scripts not to be muted.
