`FilterOperator.DoesNotContain` Does Not Work `!*ExcludeThis*`

[mavaddat]

Describe the bug

The FilterOperator.DoesNotContain filter has no effect even when paired with !*ExcludeThis* filter syntax.

To Reproduce

Steps to reproduce the behavior:

1. Use FilterOperator="FilterOperator.DoesNotContain" with FilterValue="!*Example*" or FilterValue="*Example*" within a GridColumn of a Grid
2. See that the filter actually defaults to FilterOperator.None behavior.

Expected behavior

That columns with the expected text would be hidden.
