Defining an empty enumerator is broken

Defining an empty enumerator

private static async AsyncEnumerator<int> GetEmptyEnumerator()
{
    var yield = await AsyncEnumerator<int>.Capture();

    return yield.Break();
}

yields the enumerators MoveNext method to return true on the first access while the Current property contains the default value of the type iterated (null for reference types).
