This is cause because the controller is attached to lifecycle twice during the creation.
Once in `SavedStateHandleController .create(SavedStateRegistry registry, Lifecycle lifecycle, key, Bundle defaultArgs)` when creating the controller. And a second time, in AbstractSavedStateViewModelFactory.create()` just after the controller is created:

``` AbstractSavedStateViewModelFactory.java

public final <T extends ViewModel> T create(@NonNull String key, @NonNull Class<T> modelClass) {
SavedStateHandleController controller = SavedStateHandleController.create(
mSavedStateRegistry, mLifecycle, key, mDefaultArgs);
controller.attachToLifecycle(mSavedStateRegistry, mLifecycle);
....
```
