<p>This tests scheduling requestIdleCallback when the browser is idle. WebKit should fire idle callbacks.<br>
You should see idle1, idle2, and idle3 below:</p>
<pre id="result"></pre>
<script>

if (window.testRunner) {
    testRunner.waitUntilDone();
    testRunner.dumpAsText();
}

idle1 = requestIdleCallback(() => result.textContent += 'idle1\n');

  idle2 = requestIdleCallback(() => result.textContent += 'idle2\n');
  setTimeout(() => {
    idle3 = requestIdleCallback(() => result.textContent += 'idle3\n');
  }, 1000);
}, 1000);

    cancelIdleCallback(idle1);
    cancelIdleCallback(idle2);
    cancelIdleCallback(idle3);
    result.textContent += (result.textContent.includes('idle3') ? 'PASS' : 'FAIL') + '\n';

        testRunner.notifyDone();
