URL: https://github.com/apache/datafusion/issues/27404

   ### Describe the bug
   
   A valid query gets an plan time CSE error.
   
   ### To Reproduce
   
   ```sql
   -- Fails: Internal error: Physical input schema should be the same as the one
   -- converted from logical input schema. Differences:
   --   - field nullability at index 0 [__common_expr_1]: (physical) true vs 
(logical) false.
   SELECT MIN(b IS TRUE), MAX(b IS TRUE)
   FROM (VALUES (true), (NULL)) AS t(b);
   
   -- Works: the same expression outside an aggregate
   SELECT b IS TRUE, NOT (b IS TRUE)
   FROM (VALUES (true), (NULL)) AS t(b);
   ```
   
   ### Expected behavior
   
   Query works.
   
   ### Additional context
   
   _No response_
   
   ### Willingness to contribute
   
   None
