Fix latent race in cross-origin-subframe.html

We want to priortize loading and compositing tasks till FCP which breaks this test.
Upon investigation I discovered there was a latent race between installing the
intersection observer and the initial layout leading to empty IntersectionGeometry.
Waiting for a rAF in cross-origin-subframe.html before installing the observer
fixes this.
