When I click on a item in a queue, I see following Javascript error in the console. I think this is related to the recent upgrade, but I am not sure.

Uncaught TypeError: Cannot read property 'element' of undefined.

It is referring to the h variable in the minified code in the runtime.js file in this function

&nbsp;k = function(a) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; var b = a.element.children(".nx-queue-loader");<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; b.addClass(".nx-queue-loader-ended"), b.animate({opacity: 0}, 500, "linear", function() {<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; b.remove()<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }), h.element.find(".nx-queue-item-selected").removeClass("nx-queue-item-selected"), a.element.addClass("nx-queue-item-selected")<br>&nbsp; &nbsp; &nbsp; &nbsp; };
