title: Make open fancybox modal
body: <p>I have a Fancybox with two buttons in it: Merge and Cancel. Cancel closes the fancybox and Merge posts a form and wait for the page to reload. It takes a couple of seconds for the page to reload so after the user has pressed Merge I disable the Cancel button and I would like to set the option <code>modal</code> to <code>true</code> but I can't seem to find a way to set an option on a already opened fancybox. Does anyone have any suggestion on how to do this?</p>
