// META: global=dedicatedworker,sharedworker
// The `then` handlers for `Promise.resolve()` are evaluated in the first

// Check when microtasks checkpoint is performed around importScripts().
// The expectation is: the `then` handlers are evaluated after the script
// calling importScripts() is finished, not immediately after importScripts().
// Although #clean-up-after-running-script is executed as a part of
// #run-a-classic-script for importScripts()ed scripts, but at that time
// microtasks checkpoint is NOT performed because JavaScript execution context
// stack is not empty.

// Microtasks should be executed before
// #run-a-classic-script/#run-a-module-script is completed, and thus before
// script evaluation scheduled by setTimeout().
