I can try to fix this but I don't know where the existing tests for check_inner_plan are.

@kosiew I would recommend trying to write a SQL query (or rust dataframe example) that shows the same behavior
the sql tests are in https://github.com/apache/datafusion/blob/main/datafusion/sqllogictest/test_files/unnest.slt
The dataframe test are in: https://github.com/apache/datafusion/blob/main/datafusion/core/tests/dataframe/mod.rs
