We have disovered that we get this output on the cart

<script type="text/javascript" src="/Admin/Resources/js/layout/pickadayBundle.js"></script>

The script causes an error

Uncaught TypeError: Cannot read property 'parentNode' of null
    at fixPikaWrapperPositionInDOM (pickadayBundle.js:1066)
    at pickadayBundle.js:1076

Because:

function fixPikaWrapperPositionInDOM() {
    var wrapper = document.getElementById("pika-wrapper");
    var parent = wrapper.parentNode;

in our case we don't have a "pika-wrapper"-element and since you just access wrapper.parentNode without null-check somebody in your office might owe a round of beers on Friday 

Fix

function fixPikaWrapperPositionInDOM() {
    var wrapper = document.getElementById("pika-wrapper");
    if (wrapper != null) {
        var parent = wrapper.parentNode;
