// To test workers, we need to importScripts source files in the workers.

// Since the point of this test is to test blocking of importScripts, we need

// to set up one policy that will blindly pass through URLs for use in the test

// setup, and then have additional policies for the actual test cases.

//

// For the same reason we cannot use the otherwise preferred 'META: workers'

// tag, since that test setup would be blocked as soon as trusted types

// enforcement is enabled.
