Also came across something similar, in my case it even lost some data...
```sql
DataFusion CLI v57.0.0-dev
> SET datafusion.execution.target_partitions = 1;
CREATE TABLE t(g INT NOT NULL, ts INT NOT NULL)
AS VALUES (1, 1), (1, 2), (2, 3), (2, 4);
SELECT COUNT(*) OVER (
PARTITION BY g
ORDER BY ts
ROWS BETWEEN 1 PRECEDING AND CURRENT ROW
) AS c
FROM t
ORDER BY c ASC
LIMIT 2;
0 row(s) fetched.
Elapsed 0.013 seconds.
0 row(s) fetched.

| 1 |
| 2 |

2 row(s) fetched.
Elapsed 0.013 seconds.
