idle stop not stopping idle watch.

I have ng-idle/core 11.1.0 installed in an Android Ionic Capacitor application. 

After the user logs in, the idle watch kicks in and after 5mins of idleness the user is logged out idle stop is called during the log out process, however onIdleStart is still called. 

How can I stop this. 

Ionic 5, Capacitor 3, Android 11 on S20FE using Chrome Webview.
