Intermittent CI failure on at test_files/joins.slt:3676

[alamb]

Describe the bug

The sqllogictests appear to be failing intermittently on CI.

External error: query result mismatch:
[SQL] SELECT * FROM (
    SELECT 1 as c, 2 as d
    UNION ALL
    SELECT 1 as c, 3 AS d
) as a FULL JOIN (SELECT 1 as e, 3 AS f) AS rhs ON a.c=rhs.e;
[Diff] (-expected|+actual)
-   1 2 1 3
-   1 3 1 3
+   1 3 1 3
+   1 2 1 3
at test_files/joins.slt:3676

To Reproduce

When CI runs this command cargo test -p datafusion-sqllogictest --test sqllogictests sometimes it fails

Example failure:
https://github.com/apache/arrow-datafusion/actions/runs/8724655620/job/23936183227?pr=10115

Expected behavior

The test should always pass or always fail. Not be intermittent

I think the issue is that the rows show up in a different order
