org.teiid.padSpace property does affect to "=" operator. But does not affect to "IN" operator

Issue

org.teiid.padSpace does affect to "=" operator. But does not affect to "IN" operator.

[data for a column named "id"]

"test1     "

["=" operator] I can get a result

SELECT * FROM ViewModel.originalViewTable WHERE ViewModel.originalViewTable.id ='TEST1';

["IN" operator] I can not get a result

SELECT * FROM ViewModel.originalViewTable WHERE ViewModel.originalViewTable.id IN ('TEST1', 'TEST2');
