I'm having issues with the Tooltip not working in Chrome when it is in a lightbox (modal window). It works in other browsers. Also works as expected when NOT in a lightbox. As far as I can tell, it's possibly a z-index issue. If I inspect the span element and change it's z-index (to any value) using Chromes code viewer, the tooltip shows up. But if I add a z-index value to the actual css source, nothing happens.
