Class no-footer applied to Table despite a footer is present.

I'm using Datatables 1.10.13 with the jQuery UI styling options. Somehow DataTables must think there is no footer present, as the maintable gets the class "no-footer" applied. Wouldn't bother me much, but an ugly

border-bottom: 1px;

is applied, that doesn't really fit. You even have that feature/problem on your example: https://datatables.net/manual/styling/jqueryui

• Is this a bug?
• How can I remove it without modifiying the js or css source?

I'd like to avoid using something like

$(table).removeClass("no-footer");
