Explicit column name error in CTE of UNION

Details

    Description

      The bug described in MDEV-15478 is not fully resolved. When the CTE is used again with UNION in the main statement, it gives error #1054 - Unknown column 'col1' in 'field list'

      WITH cte (col1) AS
      		 
      (
      		 
        SELECT 1
      		 
        UNION
      		 
        SELECT 2
      		 
      )
      		 
      SELECT col1 FROM cte
      		 
      -- union statement added to example in MDEV-15478
      		 
      UNION
      		 
      SELECT col1 FROM cte

      This can currently be worked around with:

      WITH cte (col1) AS
      		 
      (
      		 
        SELECT 1 AS col1 -- alias required
      		 
        UNION
      		 
        SELECT 2
      		 
      )
      		 
      SELECT col1 FROM cte
      		 
      UNION
      		 
      SELECT col1 FROM cte
