alertify doesn't remember to resize when alertifying second time

[kirkdm]

Expected behavior

I have resizeTo('70%','70%') and when I call it the second time it doesn't remember to resize it just remove the width and height

I'm navigating between routes through javascript with hash tags using Backbone.js

Actual behavior

when call the function a second time it doesn't reproduce the previous behavior it just loads a dialog without the width and height
Whats happening is that it resizes to the 70%, 70% but then it removes the width and hieght and goes to a small dialog

Steps to reproduce the behavior

alertifyApplicationError: function(message) {

	alertify.closeAll();			

	alertify.alert().setting({
		'closable': false, 
		'resizable': true,
		onshow:function() {
			$('html').css({ padding: '0px'});
		},
		onclose:function() {   
			$('html').css({ padding: '0px'});
		}	
	})
	.resizeTo('70%','70%')
	.setHeader('<i class="fa fa-times-circle fa-2x" aria-hidden="true" style="color:red"></i> <span style="line-height: 2.5; position: absolute; left: 60px; top: 12px;">Application Error</span>')        	
	.setContent(message).show();
},
