LPS-46356

Hey @mjbradford89,

Attached is an update for http://issues.liferay.com/browse/LPS-46356.  This issue still exists if we have 2 asset publishers stacked on top of each other (and don't have much content displaying in them), and the dropdown from the top one gets overlapped by the nav item on the bottom one. The root of the issue is that in css/taglib/navbar.css, @Robert-Frampton added a z-index to all navs inside of a navbar. Can you coordinate with him to see why we added that and if we can remove it?

Please let me know if you have any questions.  Thanks!
