Thank you for reporting the issue!
You are correct. It seems `.storage` holds the correct sliced part of the
array and `.storage.values` does not:
```python
(Pdb) len(pa_arr.storage.values)
1200
(Pdb) len(pa_arr.storage)
100
```
So this looks like a bug in `pyarrow.FixedSizeListArray.values`:
```python
>>> import pyarrow as pa
>>> arr = pa.array([[1, 2, 3], [], None, [4]], type=pa.list_(pa.int32()))
>>> arr.values
<pyarrow.lib.Int32Array object at 0x128665f60>
[
1,
2,
3,
4
]
>>> arr[:2].values
<pyarrow.lib.Int32Array object at 0x1286661a0>
[
1,
2,
3,
4
]
```
I think this issue https://github.com/apache/arrow/issues/35360 has the same
underlying problem.
