Summary:
The `Control` button press, that hides the current search filter, had some specific logic to make sure that the current selection remained visible. Since this is now generically supported, this is no longer needed.
Also updated the `Control` button behavior to also toggle back the search filter if needed, which was never finished in the original implementation.
Changelog: DataTable: pressing the control key can be used to temporarily turn the current search filter on and off.
