Dragging a puller shifts the object upon move

[jessegreenberg]

If you drag an object by the puller the initial translation gets way offset and the puller is detached from the mouse. It is as though this clickOffset may have changed, so Ill bet its actually a problem for all ISLC sims

    this.dragListener = new DragListener( {
      allowTouchSnag: true,
      start: event => {
        clickOffset = this.dragNode.globalToParentPoint( event.pointer.point ).x - event.target.x;
        object.isDraggingProperty.value = true;

Yes, I see this for other ISLC sims, moving to that repo.

I don't see any changes to the block of code listed, but if the Node scene graph location changed, I could see this behaving differently.

Fixed in the above commit. I didn't investigate what change to break this.
