Unable to cancel click event on buttons created in dialog

In the createButtons function of ui.dialog, the click handler for the created button is as follows:

$.each(buttons, function(name, fn) {
  $('<button/>')
    .text(name)
    .click(function() { fn.apply(self.element[0], arguments); })
    .appendTo(uiDialogButtonPane);
});

I suggest modifying the handler to return the value returned from the user function, allowing the cancellation of the event, as follows:

$.each(buttons, function(name, fn) {
  $('<button/>')
    .text(name)
    .click(function() { return fn.apply(self.element[0], arguments); })
    .appendTo(uiDialogButtonPane);
});
