I noticed that other logic also does not consider `nulls_first`, for example https://github.com/apache/datafusion/blob/36660fe10d9c0cdff62e0da0b94bee28422d3419/datafusion/expr/src/sort_properties.rs#L53 Maybe @berkaysynnada can help confirm it. -- This is an automated message from the Apache Git Service.
