// In this test we have a simple page which is scrollable, with a

// <div> does not get an initial APZC, since primary scrollable
// frame is the page's root scroll frame.

// We do this before converting the APZ test data because the conversion
// loses the order of the paints.

// single child APZC which is for the RCD (fennec case).
