| <h1>Test of requestIdleCallback deadline behavior</h1> |
| <p>This test validates that deadlines returned for requestIdleCallback are less than 50ms.</p> |
| <p>The test can pass accidentally as idle deadlines have a maximum but they can always be shorter. |
| It runs multiple times to expose potential failures.</p> |
