```
fn interleave_dictionaries<K: ArrowDictionaryKeyType>(
arrays: &[&dyn Array],
indices: &[(usize, usize)],
) -> Result<ArrayRef, ArrowError> {
let dictionaries: Vec<_> = arrays.iter().map(|x|
x.as_dictionary::<K>()).collect();
if !should_merge_dictionary_values::<K>(&dictionaries, indices.len()) {
return interleave_fallback(arrays, indices);
```
Current `interleave` actually check the function
`should_merge_dictionary_values`, which will returns true if the total value in
the dictionary will overflow, and will try to merge the them, however it is not
the case for for this dataset, and it continue calling interleave_fallback
which cause the panic
