No more header on ex-navigation Drawer

After upgrading to Expo 14, I noticed that the header section in the Drawer no longer appears. It seems that the renderHeader method in the DrawerNavigation component is no longer doing anything.

Hi-

Which navigation library are you using? Can you post source code?

I actually seemed to fix the problem over the weekend. It turned out to be a styling issue. I had some styling in place for the drawer before I upgraded Expo, and once I did something must have changed behind the scenes to cause this styling to display differently. So I removed one line of styling and it started working again.
