// setup, and then have additional policies for the actual test cases.
//
// For the same reason we cannot use the otherwise preferred 'META: workers'
// tag
// (https://web-platform-tests.org/writing-tests/testharness.html#tests-for-other-or-multiple-globals-any-js),
// since that test setup would be blocked as soon as trusted types enforcement
// is enabled.
