The following doc suggests the ability to add column comments during MV creation via the `column list` parameter.

Thus, the SQL code below is expected to generate a table where the columns `col_1` and `col_2` are commented; however, this is not the case.

Note that the underlying table for the MV, `my_streaming_table`, is a Streaming Table.

%sql
USE CATALOG my_catalog;

USE SCHEMA my_schema;

DROP MATERIALIZED VIEW IF EXISTS my_mv;

CREATE MATERIALIZED VIEW my_mv
  (col_1 COMMENT 'Column 1', col_2 COMMENT 'Column 2')
  COMMENT 'MV of a streaming table.'
AS (
  SELECT col_1 , col_2 FROM my_streaming_table
)
