/*
  Test for Bug 1420589. This test synthesizes touch events with two points. One
  hits the div element on the document and the other hits the iframe element.

  We dispatch all touch events to the same document. If we find any target that
  is not in the same document of the existed target, we try to find the ancestor
  document of the new target which is in the same as the existing target and
  dispatch touch events to it. We check the points of the touch event in reverse
  order. That means we only dispatch touch events to the document which contains
  the div element in this test and expect the div element and iframe element
  receive touch events.

  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.
