smallint values from sql query shown as data type text

Dear all,

I have a power query for a table from MS SQL Server. This table contains a column of type smallint, but the value is shown in Query as type "decimal number".

--> Why does PowerBI not detect the most fitting data type?

Here my query which leads in PowerBI June2020 update to above behavior:

let
   Source = Sql.Database("MyServer", "Reporting"),
   Query = Value.NativeQuery(Source, "
SELECT
   Equipment -- PROBLEM: is smallint, which would be shown as decimal number in PBI
   ,CAST(Equipment AS int) 'Equipment' -- WORKAROUND: by conversion to int it is shown correctly as whole number in PBI
FROM [Reporting].[dbo].[Lines]
WHERE Equipment = 13")
in
   Query
