  //   our count of enters to a certain value, to match how many exits
  //   we need to do to leave fullscreen. This is used when one exit
  //   can unwind more than one enter.
  // * "target" is where we apply this action. For "enter" action, it
  //   is the element we want to call requestFullscreen() on, and for
  //   "exit", it is the document we want to call exitFullscreen() on.
  // * "fsOuter" and "fsInner" are the expected fullscreen elements of
  //   the outer and inner document respectively after executing the
  //   action in this step. These are only checked after "enter" or
  //   "exit" actions.
