Button from background screen showing above the Overlay.

1. Explain what you did
   I have a login screen which has a Login Button. When the user clicks "forgot password" we display an Overlay. The issue is that the Login Button from the background displays above the Overlay.

Here you can see the background screen is somewhat darkened by the Overlay's background EXCEPT for the login button.

This one is even more obvious because when the keyboard pushed the background screen up, the login Button actually shows over the Overlay's content.

2. What you expected to happen
   The Overlay to cover everything in the background.

3. What actually happens
   The Button from the background shows up above the overlay.

Also please include the version of react-native-elements that you are using.
