## Which issue does this PR close? ## Rationale for this change After #15149, `flatten` stopped working for `List(FixedSizeList)` because it expected the inner fixed size list to be casted to list, which wasn't happening anymore. Looking back, #15160 correctly stopped using [ArrayFunctionSignature::Recursive](url), which I expected would make only the top level list be coerced, and it would break, but it didn't. I believe that recursive lists continued to be coerced(I didn't checked yet) And then #15149 refactored that code path with the correct behavior, exposing the issue in `flatten` ## What changes are included in this PR? ## Are these changes tested? Currently broken tests now pass ## Are there any user-facing changes? Broken path now works -- This is an automated message from the Apache Git Service.
