Fixes long delay in news slider At least on Safari 9.1.1, slippy.js would often have trouble transitioning from one news item to the next if: 1. the CSS for the list elements toggled between "display:none" and "display:block", and 2. there were three or more news items. These changes maintain the same visual appearance, but avoid the display toggle so that the JS doesn't get stuck.
