(I switched to TextField; is a bit easier for me to debug)

Intermedidate testing result:

When pressing "space", the rectangle moves correctly. When moving the cursor 
"inside" these much spaces, it also moves.

Ctrl+A leads to the box borders be of length of the complete text, not the 
visible text

I thought, following would help, but does not:


     */
     public void selectRange(int anchor, int caretPosition) {
         caretPosition = Utils.clamp(0, caretPosition, getLength());
         anchor = Utils.clamp(0, anchor, getLength());
 
+        notifyAccessibleAttributeChanged(AccessibleAttribute.SELECTION_START);
+        notifyAccessibleAttributeChanged(AccessibleAttribute.SELECTION_END);
+        notifyAccessibleAttributeChanged(AccessibleAttribute.CARET_OFFSET);
+
         TextFormatter.Change change = new TextFormatter.Change(this, 
getFormatterAccessor(), anchor, caretPosition);
         TextFormatter<
