How lock fancybox overlay without jumping to the top?

Question

I want to disable browser scrolling when fancybox opened. And next code works:

helpers: {
   overlay: {
      locked: true 
   }
},

But on mobile devices window jump to top during fancybox opening. This behavior depends at locked: true param. How can I lock overlay and prevent jumping?

Different decisions, such as:

$('html').css('overflow', 'hidden')

or

$(document.body).bind('touchmove', function(e) {
   e.preventDefault();
   e.stopPropagation();
   e.returnValue = false;
});

Works, but not in all mobile browsers!

I also had to deal with this issue and it has driven me mad. I tried nearly all options, searched all questions and answers on stackoverflow but nothing seemed to work with my ajax-lightbox. I always jumped to the top. Then I did the following:

$(".lightboxe-fancyboxWindow").fancybox({ 
    type : 'ajax',
    href : "<?php echo $_SERVER['PHP_SELF']; ?>",
    ajax: {
        type: "POST",
        data: {     
            'data1' : information1,
            'data2' : information2
        },
    },
    autoSize: false,
    width: '60%',
    beforeShow : function() {
        $("body").css({"overflow" : "hidden", "padding-right" : "17px"});
    },
    afterClose: function () {
        $("html, body").removeAttr("style");
    },
    titleShow : false,
    helpers : { 
        overlay : {
            locked : false
        },
         title : null
    },
});

What I did was to add overflow hidden on body tag and 17px padding for the fake-scrollbar .
