Expected Behavior

When replacing the segments array of a TouchBarSegmentedControl I expect the control to be completely replaced with the new values specified.

Actual Behavior

When a TouchBarSegmentedControl is created with a control that just has an icon and the segments are replaced with one that just has a label both the initial icon and the new label are show. The same happens when going from label to icon.

Screenshots

1. Start with a control that just has an icon:
   

2. Replace the control with one that just has a label. The icon remains (even if set to undefined or null):
   

3. Replace again with one that has a different icon. The label remains.
