iOS 10 causes window to shift when panning map

After upgrade to iOS 10, whole window now shifts when panning with touch interface. Same effect in Mobile Safari and Chrome.

Here's a fix:

$("#map").bind("touchmove", function(){
    $('body').bind('touchmove', function(e){e.preventDefault()});
});
$("#map").bind("touchend", function(){
    $('body').unbind('touchmove');
});
