Open a modal window in a modal window body jumps to the left

Created by: drtvader

Hello! Why when opening modal in modal, there is a shift of all the site of the body? What could be the reason? I use this code, but it only works for the first modal Thanks!

$(document).ready(function(){
    $(window).load(function(){
        var oldSSB = $.fn.modal.Constructor.prototype.setScrollbar;
        $.fn.modal.Constructor.prototype.setScrollbar = function () 
        {
            oldSSB.apply(this);
            if(this.bodyIsOverflowing && this.scrollbarWidth) 
            {
                $('.minimized-header,.b-filter--floating').css('padding-right', this.scrollbarWidth);
            }       
        }

        var oldRSB = $.fn.modal.Constructor.prototype.resetScrollbar;
        $.fn.modal.Constructor.prototype.resetScrollbar = function () 
        {
            oldRSB.apply(this);
            $('.minimized-header,.b-filter--floating').css('padding-right', '');
        }
    });
});
