LPS-42287 - On a mobile device, it is difficult to scroll through page navigation without dragging the pages

Hey @natecavanaugh,

Attached is an update for http://issues.liferay.com/browse/LPS-42287.

NOTE: "Make sure to test with a page that has child pages. There are two reasons that the drag handle isn't aligned to the right. One is that that's where the caret is located for nav items with children. The second is that on some mobile browsers have native actions when dragging near the edge of the screen, for example, if the handles were aligned to the right, in Chrome dragging the nav items would try to switch tabs." - @Robert-Frampton 

Please let me know if you have any questions.  Thanks!
