AdamGS opened a new issue, #23428: URL: https://github.com/apache/datafusion/issues/23428
### Describe the bug Calling `<Expr as ExprSchemable>::nullable` on an InSubquery expression only uses the `expr`'s nullability over the schema, and not the subquery's nullability. so it return `false` for queries with the general shape of `x_non_null IN (SELECT a_nullable FROM t)`. This will cause `ExprSimplifier` to wrongly simplify some expressions into a `lit(true)` incorrectly. ### To Reproduce _No response_ ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
