When i change the pointSize or any other propertie then only the text that is visible get's changed.

The text in the overflow is not.

function setup() {

       b.units(b.MM);

  }

function draw() {

   var t = b.text("sad", 20, 20, 100, 200);

    t.contents = TextFrameContents.placeholderText;

    b.itemHeight(t, b.itemHeight(t)/2);

    b.typo(t, "pointSize", 4);   

    b.itemHeight(t, b.itemHeight(t)*2);

}
