+//
+// Ideally, it should be sufficient to use requestAnimationFrame followed
+// by two step_timeouts, with the first step_timeout firing in between the
+// requestAnimationFrame handler and the task to deliver notifications.
+// However, the precise timing of requestAnimationFrame, the generation of
+// a new display frame (when IntersectionObserver notifications are
+// generated), and the delivery of these events varies between engines, making
+// this tricky to test in a non-flaky way.
+//
+// In particular, in WebKit, requestAnimationFrame and the generation of
+// a display frame are two separate tasks, so a step_timeout called within
+// requestAnimationFrame can fire before a display frame is generated.
+//
+// In Gecko, on the other hand, requestAnimationFrame and the generation of
+// a display frame are a single task, and IntersectionObserver notifications
+// are generated during this task. However, the task posted to deliver these
+// notifications can fire after the following requestAnimationFrame.
+//
+// This means that in general, by the time the second requestAnimationFrame
+// handler runs, we know that IntersectionObservations have been generated,
+// and that a task to deliver these notifications has been posted (though
+// possibly not yet delivered). Then, by the time the step_timeout() handler
+// runs, these notifications have been delivered.
+//
+// Since waitForNotification uses a double-rAF, it is now possible that
+// IntersectionObservers may have generated more notifications than what is
+// under test, but have not yet scheduled the new batch of notifications for
+// delivery. As a result, observer.takeRecords should NOT be used in tests:
+//
+// - myTestFunction0()
+//   - waitForNotification(myTestFunction1)
+//     - requestAnimationFrame()
+//   - Modify DOM in a way that should trigger an IntersectionObserver callback.
+// - BeginFrame
+//   - requestAnimationFrame handler runs
