Here's an example: https://snack.expo.io/@buishi/nested-navigator-headers\r\n\r\nThe example is structured like so:\r\n-- RootNavigator (stack)\r\n--- AppNavigator (stack)\r\n---- DrawerNavigator (drawer)\r\n----- App (view)\r\n\r\nAlthough headers are enabled for DrawerNavigator, the header doesn't display, nor does the title. Somehow I was able to solve this in a local project, but I can't explain why...\r\n\r\n### Expected Behavior\r\n\r\nI would expect the drawer and child headers to display, along with their titles.\r\n\r\n### How to reproduce\r\n\r\nhttps://snack.expo.io/@buishi/nested-navigator-headers\r\n\r\n### Your Environment\r\n\r\n| software         | version\r\n| ---------------- | -------\r\n| react-navigation | 1.5.8\r\n| react-native     | expo 25\r\n| node             | 8.6.0\r\n| npm or yarn      | 5.5.1\r\n"}}
