Conditional Paging not working in Firefox (v63.0.3)

I noticed that the plugin ConditionalPaging.js wasn't firing when I viewed my page in Firefox.

(https://github.com/DataTables/Plugins/blob/master/features/conditionalPaging/dataTables.conditionalPaging.js)

I thought it might be that I had conditionalPaging in quotes, but either way, when I initialize my DataTables, "conditionalPaging": true OR conditionalPaging: true wouldn't work.

I dove into the actual code and inserted a few console.logs and I found that the options variable is returning as undefined. I don't know how to resolve this. It's working fine in Chrome and Safari.

### Example JS:

$('#myTable').DataTable({
			"pageLength": 12,
			conditionalPaging: true,
			"pagingType": "simple_numbers",
			"searching": true,
			"dom": '<"top"fp<"clear">>rt<"bottom"p<"clear">>',
			"language": {
				"search": "",
				"searchPlaceholder": "Search Wish List",
				"paginate": {
					"first": "<<",
					"previous": "<",
					"next": ">",
					"last": ">>",
				}
			},
			"columnDefs": [{
				"targets": [0, 1],
				"orderable": false
			}],
			"order": [],
			"initComplete": function(settings, json) {
				
				$(".dataTables_wrapper .top").addClass("row mb-3");
				$(".dataTables_wrapper .bottom").addClass("row mb-3");
				$(".dataTables_wrapper .top .dataTables_filter").addClass("mt-0 col-8 col-md-6 text-left");
				$(".dataTables_wrapper .top .dataTables_filter input").addClass("form-control form-control-sm mx-0");
				$(".dataTables_wrapper .top .dataTables_paginate").addClass("mt-0 pl-0 col-4 col-md-6 text-right");
				$(".dataTables_wrapper .bottom .dataTables_paginate").addClass("pl-0 col-12 text-right");
			}
		});

edit: I am using DataTables 1.10.19

Start with features/conditionalPaging/dataTables.conditionalPaging.js and reproduce the issue in Firefox 63.0.3 using the initialization example. Inspect why the options variable is undefined, then verify that conditionalPaging works in Firefox while remaining functional in Chrome and Safari.
