## Summary
<!--Explain briefly what goes wrong and explain why you believe this is a bug and not the intended behavior of SQLite (if it is not a crash).-->**No review yet**

## Minimized query

```sql
CREATE TABLE T (
  a TEXT,
  b TEXT,
  c REAL
);
INSERT INTO T VALUES ('a','b',5.0), ('a','c',5.0), ('b','d',-8.25);
SELECT a,b,c,
RANK() OVER (PARTITION BY a ORDER BY c DESC) AS d FROM T;
UPDATE T SET a = CURRENT_TIMESTAMP WHERE a IS NOT NULL;
INSERT INTO T SELECT * FROM T;
UPDATE T SET c = c + 1 WHERE 1 RETURNING *;
```

## Actual output

```sql
a|b|5.0|1
a|c|5.0|1
b|d|-8.25|1
2026-05-15 11:30:08|b|6
2026-05-15 11:30:08|c|6
2026-05-15 11:30:08|d|-7.25
2026-05-15 11:30:08|b|6
2026-05-15 11:30:08|c|6
2026-05-15 11:30:08|d|-7.25
```

## Expectation

```sql
a|b|5.0|1
a|c|5.0|1
b|d|-8.25|1
2026-05-15 11:30:08|b|6.0
2026-05-15 11:30:08|c|6.0
2026-05-15 11:30:08|d|-7.25
2026-05-15 11:30:08|b|6.0
2026-05-15 11:30:08|c|6.0
2026-05-15 11:30:08|d|-7.25
```
