+ // 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."
