Description

I am starting a Headless JS task when I receive a push notification when the app is in not in foreground. In my Headless JS task I perform some logic and then I will use Linking.openURL('myapp://myapp') to launch the app.

In cases where the app is running in the background, the Linking.openURL will bring the app to foreground, but it will remount the entire app, as if I was launching it for the first time.

This would be fine, as long as the "old" app to be unmounted, but it's as if the "old" app is also running, so all my event listeners and react lifecycle methods run double. As if I was running two instances of the app simultaneously.

I'm not sure how to make a reproduction case for this, @rcidt - is there any chance you can make something simple, it'd make it much easier to diagnose
