>  IntersectionObserver WPTs expect that intersection observations are

>  expectation holds in Blink, but doesn't necessarily hold in other engines.
>  In WebKit, requestAnimationFrame and layout are separate tasks, so it's
>  possible for the first step_timeout to fire in between rAF and layout,
>  leading to test flakiness. This CL makes tests wait for an additional
>  step_timeout to account for this.
