[BUG] closeOnConfirm to false break tab button

[Buom01]

Hi,
I find a bug (tested in firefox):
in a form, you can press tab to go to the next input, but after this code:

swal({
    title: "Simple question",
    closeOnConfirm: false,
},function(){
    window.setTimeout(function(){
        swal("Simple confirmation", "and tab breaking", "success");
    },0);
});

you can't use tab button in form anymore :(

Temporary solution find in: #391

The same issue is here. Solution is window.onkeydown = null in onClose callback

Closing since it's a duplicate of #391. Will investigate soon.
