Node size don't go back auto stretch

If you don’t set desiredSize explicitly, the node size will auto stretch, e.g. when adding more text, Now I need it reverse, I resize node by mouse to any size, then press the button delete the size property, but it not automatically go back to the auto stretch mode.

press the button try it.

You need to reset the Part.resizeObject’s desiredSize to NaN x NaN.

thank you walter, by the way, I made a sample for this.
