### Backend CH (ClickHouse) ### Bug description [Expected behavior] and [actual behavior]. We have an expression `if(a, x, y)`, where `x` and `y` have types ``` x: Map(String, Tuple(sixty_days Tuple(num1 Nullable(Int32),num2 Nullable(Int32)) y: Map(String, Tuple(sixty_days Tuple(num1 Nullable(Int32),num2 Nullable(Int32)) ``` but the result type of the `if` expression is ``` Map(String, Tuple(Tuple(num1 Nullable(Int32),num2 Nullable(Int32)) ``` The diff is caused by `DB::getLeastSupertype`, which is used to determine the result type. ### Gluten version _No response_ ### Spark version None ### Spark configurations _No response_ ### System information _No response_ ### Relevant logs ```bash ``` -- This is an automated message from the Apache Git Service.
