Current behavior

The user cannot select a filter operator if the filter input doesn't have entered data.

Expected behavior

The user should be able to pre-select a filter operator no matter if there is data entered in the filter input or not.

Minimal reproduction of the problem with instructions

1. Open this StackBlitz example
2. In the Product Name column, I click the filter operator button
3. Select "Ends with"
4. Click the filter operator button again and see that "Ends with" is not selected.
5. Type "g" in the filter text field. Grid updates but doesn't filter the data by "Ends with" filter.
6. Click the filter operator button and see that "Contains" is selected instead of "Ends with"
7. Select "Ends with" once more and Grid filters correctly
