ui.tab spinner in 1.5 still broken


Hi,
the spinner in 1.5 is still broken (doesn't show)!
This is from beta 4 which worked fine:
if (o.spinner) {
var $span = $('span', a);
$span.data('label.tabs', $span.html()).html('<em>' + o.spinner + '</
em>');
}
The same in 1.5:
if (o.spinner) {
var label = inner(a).html();
inner(a).wrapInner('<em></em>')
.find('em').data('label.tabs', label).html(o.spinner);
}
When I put the beta4 code into 1.5, the spinner shows again, but isn't
removed anymore!
