Placeholder values erased when clicking any link on the page

I've run into an error whenever I click a link on the page (for a Modal or expanding menu) all of the placeholder values on the page get erased. I can fix the problem if I comment out the following lines:

jquery-placeholder/jquery.placeholder.js

Lines 114 to 118 in bc98c21

    
           $(window).bind('beforeunload.placeholder', function() { 
        
           	$('.'+settings.customClass).each(function() { 
        
           		this.value = ''; 
        
           	}); 
        
           });

Is this necessary to have in there since we already have a form submit listener?

Should be fix.

	$(window).bind('beforeunload.placeholder', function() {
	$('.'+settings.customClass).each(function() {
	this.value = '';
	});
	});
