executeEnteringTransition = (node, done) => {
  /* same code */
    complete: () => {
      tween({ from: windowScroll.get('top'), to: 0 }).start({
        update: v => windowScroll.set('top', v),
        complete: () => {
          // this removes all style from the post node
          // and fixes the close icon position bug
          // https://stackoverflow.com/questions/42660332/css-transform-parent-and-fixed-child-is-there-a-way-to-breakout-of-node-with-tr
          
          this.post.style = null; 
          done();
        }
      });
    }
  });
