I create a custom button that allows me to do some stuff over the map. I press the fullscreen button and it disappears.
I tried to play with the console and take it forward with z-index and other stuff.

This is my code in codesandbox for the bug.
Please press on the "open in a new window" to get the fullscreen button.
Thanks!
With MapControl component.
<MapControl position={google.maps.ControlPosition.BOTTOM_CENTER}>
<div>That was easy</div>
</MapControl>

fullscreen mode creates inside it element. You should add your button after it creates, in React you can do it with ReactDOM.createPortal. Here you should add your btn: document.getElementById('your-map-id').getElementsByTagName('div')[0]
