  When a new window is opened through window.open() it will contain the initial
  empty document. If the URL parameter is set to about:blank, it will stay on
  the initial empty document (unlike iframes with src="about:blank", which will
  start a navigation to a non-initial about:blank document).
  These tests verify the behavior of navigations that happen on the initial
  empty document in that situation. They should all be converted to do a
  replacement.
