     21**Edit:**[[BR]]
     22Native way to reproduce:
     23{{{
     24window.onbeforeunload = function(){
     25        return 'beforeunload';
     26};     
     27}}}
     28
     29Below causes onbeforeunload only in IE9 and IE10 (mentioned in #10484):
     30{{{
     31window.attachEvent('onbeforeunload', function() {
     32        return 'You will lose your content.';
     33});
     34}}}
