Seems that this is not a bug, rather a normal behaviour of the app.

Saved instance state bundles persist through both configuration changes and process death, use saved instance state to store a minimal amount of data necessary, such as an ID, to re-create the data necessary to restore the UI back to its previous state should the other persistence mechanisms fail. Most apps should implement this to handle system-initiated process death.

I can't reproduce this with the latest main code. Please re-open if you can still reproduce.

@alexvanyo open the app scroll the list switch to other app exec adb shell am kill com.google.samples.apps.nowinandroid to simulate the system-initiated process death come back to this app the scroll position of list is lost

Interesting, only the scroll position of for you tab is not saved, the scroll position of other lists is stored normally. I think this is a bug.
