Cant clear with 'Allow clear' and 'Select on Close' properties both enabled.

[LetMeSolveThat4You]

While i tried to clear a selected value, i noticed that i can't leave the widget without selecting at least something. This behaviour occurs when the 'select on close' property is enabled.

when i press the cross icon (to clear the widget) the dropdown appears and i can't ESC out or select a blank row.

The workaround for this it to create a searchstring where nothing is found and then leave the widget, however i think this can be solved more elegantly.
