  // Note: According to html spec: https://html.spec.whatwg.org/#attr-fe-autofocus,

  // topDocument's autofocus processed flag initially is false and is set to true

  // after flushing autofocus candidates, i.e. flush of autofocus candidates

  // only happens once per page load.

  // In order to test the behaviour with both focus-without-user-activation on and off:

  // two test files are necessary:

  // - focus-without-user-activation-disabled-tentative.html

  // - focus-without-user-activation-enabled-tentative.sub.html

  // Use same origin url here because when iframe document has cross origin

  // url, autofocus will be blocked by default with following console error:

  // "Blocked autofocusing on a form control in a cross-origin subframe."
