When working with multi-select if you select more than 1 item and then unselect them all programmatically by passing [] the drop down does not re-render to its original state with label inside it. The dropdown trigger becomes blank and the label outline is still present.

If only 1 item is selected and you unselect it by setting its value to [] than it works correctly, the label moves to the middle of the dropdown trigger and the outline label is removed.

Repeatable every time.
