Part 3 - Adding scale to transition from drag and compensate viewport scroll in this.to

Post.js

onExit = () => {
  this.removeListeners();
  if (!this.preview) return;

  const scale = 1 - this.state.dragProgress * (1 - DRAG_MINIMUM_SCALE);

  this.from = {
    top: 0,
    height: this.post.offsetHeight,
    width: this.post.offsetWidth,
    borderRadius: this.postStyler.get('borderRadius'),
    scale, // add scale right there
    scrollTop: windowScroll.get('top')
  };
  
  this.to = {
    ...this.getPreviewStyleAndPosition(),
    scrollTop: 0
  };
  // setting destination top to compensate
  // for the drag
  if (this.isTransitioningFromDrag) {
    this.to.top += windowScroll.get('top');
  }
  
  /* same code */
};
