/*
  Test for Bug 1420589. This test synthesizes touch events with two points. The
  first one hits iframe1 and the other hits iframe2.

  We dispatch all touch events to the same document. We stop dispatching touch
  events to a target if we can't find any ancestor document that is the same as
  the document of the existing target. We check the points of the touch event in
  reverse order. That means we choose the document of iframe2 as our targeted
  document. We won't dispatch touch events to the document of iframe1 nor the
  parent document of iframe1 and iframe2.

  We dispatch pointer events to the hit targets even when there aren't in the
  same document. This test expects that pointer events are dispatched to the div
  element and the iframe document.
