### Describe the bug Datafusion substrait does not set 'maintain_singular_struct' in MaskExpression https://github.com/substrait-io/substrait/blob/aab01537d750f6fb296a7fe8e18299d04ecc7a83/proto/substrait/algebra.proto#L1298-L1300 ### To Reproduce Generate the substrait plan from the following SQL SQL ``` SELECT PS_AVAILQTY FROM 'partsupp' ORDER BY PS_AVAILQTY ``` The following substrait plan will be generated: ``` { "relations": [ { "root": { "input": { "fetch": { "input": { "sort": { "input": { "read": { "baseSchema": { "names": [ "ps_partkey", "ps_suppkey", "ps_availqty", "ps_supplycost", "ps_comment" ] }, "projection": { "select": { "structItems": [ { "field": 2 } ] } }, "namedTable": { "names": [ "partsupp" ] } } }, "sorts": [ { "expr": { "selection": { "directReference": { "structField": {} } } }, "direction": "SORT_DIRECTION_ASC_NULLS_LAST" } ] } }, "count": "10" } }, "names": [ "ps_availqty" ] } } ], "version": { "minorNumber": 51, "producer": "datafusion" } } ``` projection doesn't include 'maintain_singular_struct' and therefore fails when running the plan through the substrait-validator ``` "projection": { "select": { "structItems": [ { "field": 2 } ] } }, ``` ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
