Ouch! on the nail, thanks Andy.

LzView.getAttributeRelative will do the job.

I just wrote something like this, but I think it has the same bug as 3.3:

  <method name="getGlobal" args="obj,attr">
    var rv = obj[attr];
    while(true) {
      if(obj instanceof lz.canvas) {
        return(rv);
      }
      obj = obj.parent;
      rv += obj[attr];
    }
  </method>
