Now if the old `initSelection` method is used, a warning will be triggered in the console informing the user that it has now been changed to `DataAdapter.current`, and they should create a custom data adapter instead. We will still only call `initSelection` once, and then default back to the old data adapter for calls after that. This allows for mostly transparent support between versions. This adds tests to ensure that `initSelection` operates the same as it previously did, but now patches the `current` method of the default data adapter.
