Order by is omitted when projection is raised above ordering with grouping

I have a SQL which contain constants in the Select clause and also it contains Group By, Order By and Limit clauses in the SQL.
When I execute the SQL, the Order By clause is not being pushed to the underlying translator. My translator doesn't support "SelectExpressions" i.e. supportsSelectExpression() returns false.
When I remove the constant from the Select clause then the Order By is pushed to the translator.

Is this a bug in Teiid's query Optimizer?

The following are the sample queries and attached are the Query Plans for both the SQL's.

Query1: This SQL doesn't push the Order By clause to the translator.

SELECT B.RESCLASS, COUNT AS GROUPING_COUNT, 'SECURITY.BASERULE' AS "_objecttype_" FROM
SECURITY.BASERULE AS B GROUP BY B.RESCLASS ORDER BY B.RESCLASS DESC LIMIT 22

Query2: This SQL pushes the Order By to the translator.

SELECT B.RESCLASS, COUNT AS GROUPING_COUNT FROM
SECURITY.BASERULE AS B GROUP BY B.RESCLASS ORDER BY B.RESCLASS DESC LIMIT 22
