### Describe the bug, including details regarding any error messages, version, and platform. Hi, In some (rather specific) situations, the following filter expression: `pyarrow.compute.field("x").isin([0.0])` incorrectly filters out matching rows. Here is a minimal reproducer: ```python from tempfile import TemporaryDirectory import pyarrow.compute import pyarrow.dataset import pyarrow.parquet data = pyarrow.table({"x": [0.0]}) f0 = pyarrow.compute.field("x") == 0.0 f1 = pyarrow.compute.field("x").isin([0.0]) with TemporaryDirectory() as tmpdir: pyarrow.parquet.write_to_dataset(data, tmpdir) assert data == pyarrow.dataset.dataset(tmpdir).to_table() assert data == pyarrow.dataset.dataset(tmpdir).filter(f0).to_table() assert data == (actual := pyarrow.dataset.dataset(tmpdir).filter(f1).to_table()), actual ``` Output: ``` Traceback (most recent call last): File "/tmp/tmp.iectDMOJmW/test.py", line 18, in <module> assert data == (actual := pyarrow.dataset.dataset(tmpdir).filter(f1).to_table()), actual AssertionError: pyarrow.Table x: double ---- x: [[]] ``` This does not happen if `x` contains other values that are not `0.0` ( `pyarrow.table({"x": [0.0, 1.0]})` --> ✅ | `pyarrow.table({"x": [0.0, 0.0, 0.0]})` --> 💥). ### Component(s) Python, C++ -- This is an automated message from the Apache Git Service.
