Drawer rendering issue with React 16 on android and web

[wickedest]

First of all, thanks for carbon-ui. It looks amazing so far and I am eager to use it to create an android/web application. It took me a while, but I got the example application working for (android/web) here: https://gitlab.com/jamie-peabody/places-carbon

I need to use react 16.3.0-alpha.1, webpack 4, react-native-web, and carbon-ui. I am getting some issues.

The android app behaves well enough, but it renders the drawer below the AppBar.

The web app is broken. There are two issues with it:

1. The Drawer is not fully hidden, extending into the main application. It appears to be a responsive width issue. If I make the browser smaller, the Drawer hides (mostly). Its shadow is still visible.
2. The Drawer renders below the AppBar on android.

Clicking to open the Drawer results in an exception: Uncaught ReferenceError: regeneratorRuntime is not defined the app was missing babel-polyfill. opening the Drawer correctly renders above the AppBar on web.
