This appears to be the jquery function that is triggering the error, but I have no idea why:
function () {
var t,
n,
r = N.createElement('div');
for (t in {
submit: !0,
change: !0,
focusin: !0
}) n = 'on' + t,
(c[t + 'Bubbles'] = n in e) || (r.setAttribute(n, 't'), c[t + 'Bubbles'] = !1 === r.attributes[n].expando);
r = null
}();
var V = /^(?:input|select|textarea)$/i,
J = /^key/,
Y = /^(?:mouse|pointer|contextmenu)|click/,
G = /^(?:focusinfocus|focusoutblur)$/,
Q = /^([^.]*)(?:\.(.+)|)$/;
specifically, this is the line that gets highlighted when the error occurs:
(c[t + 'Bubbles'] = n in e) || (r.setAttribute(n, 't'), c[t + 'Bubbles'] = !1 === r.attributes[n].expando);
