7.1 + 7.1.1 Broken style

I’m not sure if this was present in 7.0.3 – it is present in 7.1 and 7.1.1 …

I am displaying entire library with a search bar.

When I search a word that either does or does not have results, an extra <span> is displayed at the bottom of the page that should not be visible …

Looks like there are no rules for the .ui-helper-hidden-accessible class …

        <span role="status" aria-live="assertive" aria-relevant="additions" class="ui-helper-hidden-accessible">
            <div style="display: none;">No search results.</div>
            <div>No search results.</div>
        </span>

The page I need help with: [log in to see the link]
