Automatic update from web-platform-tests Tests for requestIdleCallback deadline computation (#31177) * Tests for requestIdleCallback deadline computation Deadline should be: - capped at 50ms - capped at 1000/60 (~16ms) when there is a pending rAF callback - capped at the time of the next timeout - be updated when the above conditions change, during the callback itself See https://github.com/whatwg/html/pull/7166 Co-authored-by: Philip Jägenstedt <philip@foolip.org> -- wpt-commits: 6ae31b2052754cb7645ba0e4c7c8ec43681d4a36 wpt-pr: 31177

<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>
