Javascript error when buying ticket on Edge browser

The undefined or null reference is presumably for who.match('self'), which is defined as var who = $('#order-form')[0].elements.who.value;.

It'd be helpful to know the result of evaluating each of the following in the console:

$('#order-form')
$('#order-form')[0]
$('#order-form')[0].elements
$('#order-form')[0].elements.who
$('#order-form')[0].elements.who.value
