   Has it already been fixed?
   
   ```rust
   fn test_fixed_size_binary_array_from_sparse_iter() {
       let none_option: Option<[u8; 32]> = None;
       let input_arg = vec![none_option, none_option, none_option, none_option];
       let arr =
           FixedSizeBinaryArray::try_from_sparse_iter(input_arg.into_iter()).unwrap();
       assert_eq!(0, arr.value_length());
       assert_eq!(4, arr.len())
   }
   ```
   
   I create and run this unit test, and it is ok.
